<p>O <b>espectro visível</b>, ou <b>espectro óptico</b>, ou <b>luz visível</b>, é a porção do <a href="/wiki/Espectro_eletromagn%C3%A9tico" title="Espectro eletromagnético">espectro eletromagnético</a> cuja <a href="/wiki/Radia%C3%A7%C3%A3o_eletromagn%C3%A9tica" title="Radiação eletromagnética">radiação</a> é composta por <a href="/wiki/F%C3%B3ton" class="mw-redirect" title="Fóton">fótons</a> capazes de sensibilizar o <a href="/wiki/Olho_humano" title="Olho humano">olho humano</a> de uma pessoa normal. </p><p>Esta faixa visível do espectro eletromagnético é delimitada junto à mais baixa frequência oticamente estimulante - percebida como vermelha - pela sugestivamente nomeada faixa de <a href="/wiki/Radia%C3%A7%C3%A3o_infravermelha" title="Radiação infravermelha">radiação infravermelha</a>, e pelo lado da mais alta frequência perceptível - entendida como violeta - pela nomeada de forma igualmente sugestiva faixa de <a href="/wiki/Radia%C3%A7%C3%A3o_ultravioleta" title="Radiação ultravioleta">radiação ultravioleta</a>. </p><p>O espectro visível pode ser dividido em subfaixas de acordo com a cor, com a subfaixa do vermelho abarcando os comprimentos de onda longos, a subfaixa do verde ao centro e a subfaixa do violeta abarcando aos comprimentos de onda mais curtos, subdivisões essas facilmente identificáveis na ilustração acima ou mesmo em um arco-íris. Os <a href="/wiki/Comprimentos_de_onda" class="mw-redirect" title="Comprimentos de onda">comprimentos de onda</a> nessa faixa de radiação estão compreendidos entre 370 nm (violeta) e 750 nm (vermelho),<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span>[</span>1<span>]</span></a></sup> sendo comum afirmar-se por aproximação que os comprimentos de onda dessa faixa localizam-se entre os 400 e 700 <a href="/wiki/Nan%C3%B4metros" class="mw-redirect" title="Nanômetros">nanômetros</a> (nm). Em termos de frequência, tem-se por correspondência que o espectro visível define-se pela banda situada entre 400 <a href="/wiki/Tera" title="Tera">T</a>Hz e 790 T<a href="/wiki/Hertz" title="Hertz">Hz</a>. </p><p>O espectro visível não apenas é dependente da espécie como também varia muito de uma espécie animal para a outra. Os <a href="/wiki/C%C3%A3o" title="Cão">cachorros</a> e os <a href="/wiki/Gato" title="Gato">gatos</a>, por exemplo, não veem todas as <a href="/wiki/Cor" title="Cor">cores</a> que os humanos veem, percebendo do nosso espectro visível apenas as sub-faixas do azul à amarela. Enxergam contudo geralmente bem em <a href="/wiki/Preto" title="Preto">preto</a> e <a href="/wiki/Branco" title="Branco">branco</a>, numa nuance de cinzas. Já as <a href="/wiki/Cobra" title="Cobra">cobras</a> veem no <a href="/wiki/Infravermelho" class="mw-redirect" title="Infravermelho">infravermelho</a> e as <a href="/wiki/Abelha" title="Abelha">abelhas</a> no <a href="/wiki/Ultravioleta" class="mw-redirect" title="Ultravioleta">ultravioleta</a>, faixas para as quais somos cegos. Conforme dito, nós <a href="/wiki/Humano" title="Humano">humanos</a> vemos numa faixa que vai do <a href="/wiki/Vermelho" title="Vermelho">vermelho</a> ao <a href="/wiki/Violeta_(cor)" title="Violeta (cor)">violeta</a>, passando pelo <a href="/wiki/Verde" title="Verde">verde</a>, o <a href="/wiki/Amarelo" title="Amarelo">amarelo</a> e o <a href="/wiki/Azul" title="Azul">azul</a>, contudo mesmo entre os humanos pode haver grandes variações quanto aos detalhes da faixa percebida. Em particular os limites do espectro ótico variam muito de espécime para espécime. Pessoas <a href="/wiki/Daltonismo" title="Daltonismo">daltônicas</a> costumam ter dificuldades em visualizar cores contidas em certas faixas do espectro. </p> <figure class="mw-halign-center" typeof="mw:File/Thumb"><a href="/wiki/Ficheiro:Electromagnetic_spectrum_-pt.svg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/3/36/Electromagnetic_spectrum_-pt.svg/650px-Electromagnetic_spectrum_-pt.svg.png" decoding="async" width="650" height="199" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/3/36/Electromagnetic_spectrum_-pt.svg/975px-Electromagnetic_spectrum_-pt.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/3/36/Electromagnetic_spectrum_-pt.svg/1300px-Electromagnetic_spectrum_-pt.svg.png 2x" data-file-width="1176" data-file-height="360" /></a><figcaption>Espectro eletromagnético completo (clique para ampliar)</figcaption></figure> <figure typeof="mw:File/Thumb"><a href="/wiki/Ficheiro:Newton%27s_color_circle.png" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/c/c0/Newton%27s_color_circle.png/278px-Newton%27s_color_circle.png" decoding="async" width="278" height="286" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/c/c0/Newton%27s_color_circle.png/417px-Newton%27s_color_circle.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/c/c0/Newton%27s_color_circle.png/556px-Newton%27s_color_circle.png 2x" data-file-width="788" data-file-height="810" /></a><figcaption>O círculo colorido de Newton, do livro <a href="/wiki/Opticks" title="Opticks">Opticks</a> de 1704, que relaciona as cores com as notas, sendo, a relação uma oitava completa.</figcaption></figure> <figure typeof="mw:File/Thumb"><a href="/wiki/Ficheiro:Female_in_red_pullover_and_blue_jeans_-coloured_lights-2Nov2003.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/3/38/Female_in_red_pullover_and_blue_jeans_-coloured_lights-2Nov2003.jpg/280px-Female_in_red_pullover_and_blue_jeans_-coloured_lights-2Nov2003.jpg" decoding="async" width="280" height="187" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/3/38/Female_in_red_pullover_and_blue_jeans_-coloured_lights-2Nov2003.jpg/420px-Female_in_red_pullover_and_blue_jeans_-coloured_lights-2Nov2003.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/3/38/Female_in_red_pullover_and_blue_jeans_-coloured_lights-2Nov2003.jpg/560px-Female_in_red_pullover_and_blue_jeans_-coloured_lights-2Nov2003.jpg 2x" data-file-width="1024" data-file-height="683" /></a><figcaption>Iluminação com três diferentes fontes; vermelha, verde e azul.</figcaption></figure> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="História"><span id="Hist.C3.B3ria"></span>História</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Espectro_vis%C3%ADvel&amp;veaction=edit&amp;section=1" title="Editar secção: História" class="mw-editsection-visualeditor"><span>editar</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Espectro_vis%C3%ADvel&amp;action=edit&amp;section=1" title="Editar código-fonte da secção: História"><span>editar código-fonte</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>No <a href="/wiki/S%C3%A9culo_XVII" title="Século XVII">século XVII</a>, as explicações do espectro óptico vieram de <a href="/wiki/Isaac_Newton" title="Isaac Newton">Isaac Newton</a>, quando ele escreveu o livro <i><a href="/wiki/Opticks" title="Opticks">Opticks</a></i>.

Todos os tipos de radiações eletromagnéticas transportam-se no vácuo com velocidade de 3X10<sup>8</sup> m/s (<a href="/wiki/Velocidade_da_luz" title="Velocidade da luz">velocidade da luz</a>). A radiação luminosa é periódica, isto é, o padrão de picos ou depressões repetem-se em intervalos regulares. A distância entre dois picos ou duas depressões é chamado comprimento de onda. O tempo que a radiação emite um comprimento de onda é chamado de período da onda eletromagnética, a quantidade de períodos que são emitidos por segundo é chamado de frequência. O comprimento de onda está diretamente relacionado com a frequência. Se o comprimento de onda é longo, existirão menos ciclos da onda passando por um ponto por segundo (baixa frequência). Se há mais ciclos da onda passando por um ponto por segundo, o comprimento de onda será menor.<sup id="cite_ref-brown_5-0" class="reference"><a href="#cite_note-brown-5"><span>[</span>5<span>]</span></a></sup> Essa relação é dada através da equação: </p> <center> <p><span class="mwe-math-element"><span class="mwe-math-mathml-display mwe-math-mathml-a11y" style="display: none;"><math display="block" xmlns="http://www.w3.org/1998/Math/MathML" alttext="{\displaystyle \eta \lambda =c}"> <semantics> <mrow class="MJX-TeXAtom-ORD"> <mstyle displaystyle="true" scriptlevel="0"> <mi>&#x03B7;<!-- η --></mi> <mi>&#x03BB;<!-- λ --></mi> <mo>=</mo> <mi>c</mi> </mstyle> </mrow> <annotation encoding="application/x-tex">{\displaystyle \eta \lambda =c}</annotation> </semantics> </math></span><img src="https://wikimedia.org/api/rest_v1/media/math/render/svg/2bb885c7d6b9f528ffa469698a4e3035fd836094" class="mwe-math-fallback-image-display mw-invert skin-invert" aria-hidden="true" style="vertical-align: -0.838ex; width:6.63ex; height:2.676ex;" alt="{\displaystyle \eta \lambda =c}"></span> </p> </center> <p>onde, </p><p><span class="mwe-math-element"><span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="display: none;"><math xmlns="http://www.w3.org/1998/Math/MathML" alttext="{\displaystyle \eta }"> <semantics> <mrow class="MJX-TeXAtom-ORD"> <mstyle displaystyle="true" scriptlevel="0"> <mi>&#x03B7;<!-- η --></mi> </mstyle> </mrow> <annotation encoding="application/x-tex">{\displaystyle \eta }</annotation> </semantics> </math></span><img src="https://wikimedia.org/api/rest_v1/media/math/render/svg/e4d701857cf5fbec133eebaf94deadf722537f64" class="mwe-math-fallback-image-inline mw-invert skin-invert" aria-hidden="true" style="vertical-align: -0.838ex; width:1.169ex; height:2.176ex;" alt="{\displaystyle \eta }"></span> é a frequência </p><p><span class="mwe-math-element"><span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="display: none;"><math xmlns="http://www.w3.org/1998/Math/MathML" alttext="{\displaystyle \lambda }"> <semantics> <mrow class="MJX-TeXAtom-ORD"> <mstyle displaystyle="true" scriptlevel="0"> <mi>&#x03BB;<!-- λ --></mi> </mstyle> </mrow> <annotation encoding="application/x-tex">{\displaystyle \lambda }</annotation> </semantics> </math></span><img src="https://wikimedia.org/api/rest_v1/media/math/render/svg/b43d0ea3c9c025af1be9128e62a18fa74bedda2a" class="mwe-math-fallback-image-inline mw-invert skin-invert" aria-hidden="true" style="vertical-align: -0.338ex; width:1.355ex; height:2.176ex;" alt="{\displaystyle \lambda }"></span> é o comprimento de onda </p><p><span class="mwe-math-element"><span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="display: none;"><math xmlns="http://www.w3.org/1998/Math/MathML" alttext="{\displaystyle c}"> <semantics> <mrow class="MJX-TeXAtom-ORD"> <mstyle displaystyle="true" scriptlevel="0"> <mi>c</mi> </mstyle> </mrow> <annotation encoding="application/x-tex">{\displaystyle c}</annotation> </semantics> </math></span><img src="https://wikimedia.org/api/rest_v1/media/math/render/svg/86a67b81c2de995bd608d5b2df50cd8cd7d92455" class="mwe-math-fallback-image-inline mw-invert skin-invert" aria-hidden="true" style="vertical-align: -0.338ex; width:1.007ex; height:1.676ex;" alt="{\displaystyle c}"></span> é a velocidade da luz no vácuo </p> <figure class="mw-halign-right" typeof="mw:File/Thumb"><a href="/wiki/Ficheiro:Sine_waves_different_frequencies.svg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/6/6d/Sine_waves_different_frequencies.svg/283px-Sine_waves_different_frequencies.svg.png" decoding="async" width="283" height="106" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/6/6d/Sine_waves_different_frequencies.svg/425px-Sine_waves_different_frequencies.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/6/6d/Sine_waves_different_frequencies.svg/566px-Sine_waves_different_frequencies.svg.png 2x" data-file-width="400" data-file-height="150" /></a><figcaption>Relação entre a frequência da luz e o comprimento de onda.
