Die hedendaagse teorie oor lig het sy beslag gekry uit die kennis oor die reglynige voortplanting van lig (uit die Oudheid), die voorstelling van lig as golwe of deeltjies (17e eeu) en die ontdekking dat lig ander lig kan uitdoof (19e eeu). Die snelheid waarmee lig voortgeplant word, blyk 'n fundamentele grootheid te wees wat 'n belangrike rol speel in die formulering van die <a href="/wiki/Relatiwiteitsteorie" title="Relatiwiteitsteorie">relatiwiteitsteorie</a>. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Teorie">Teorie</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Lig&veaction=edit&section=1" title="Wysig afdeling: Teorie" class="mw-editsection-visualeditor"><span>wysig</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Lig&action=edit&section=1" title="Edit section's source code: Teorie"><span>wysig bron</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Reeds van oudsher af was dit bekend dat lig reglynig voortplant, ken die mens die begrip "ligstraal" en is die gedrag van ligstrale by weerkaatsing en breking ondersoek. Die eerste wet wat die breking van lig by die oorgang van een medium na 'n ander korrek beskryf, is egter eers in die 17e eeu deur <a href="/wiki/Willebrord_Snellius" title="Willebrord Snellius">Willebrord Snellius</a> (1591-1626) geformuleer. </p><p>In ŉ poging om die wet van Snellius te verklaar, het <a href="/wiki/Isaac_Newton" title="Isaac Newton">Isaac Newton</a> (1643-1727) vir hom 'n ligstraal as ŉ bundel klein deeltjies voorgestel. Die deeltjies sou volgens Newton in 'n ruimte reglynig voortgeplant en teen 'n spieël weerkaats word, byna soos wanneer korreltjies teen ŉ harde wand bots. By breking sou die deeltjies volgens die wet van Snellius dan stadiger in lug (yl) as in <a href="/wiki/Water" title="Water">water</a> of <a href="/wiki/Glas" title="Glas">glas</a> (dig) voortbeweeg. </p><p>In teenstelling met <a href="/wiki/Newton_se_bewegingswette" title="Newton se bewegingswette">Newton</a>, het <a href="/wiki/Christiaan_Huygens" title="Christiaan Huygens">Christiaan Huygens</a> (1629-1695) lig as golwe beskou en in sy werk <i>Traité de la lumière</i> te kenne gegee dat lig soos geluidsgolwe in die lug of soos oppervlakgolwe in water voortgeplant is. Om die voortplanting van liggolwe deur 'n <a href="/wiki/Lugleegte" class="mw-redirect" title="Lugleegte">lugleegte</a> te verklaar, het hy veronderstel dat daar 'n uiters dun <a href="/w/index.php?title=Flu%C3%AFdum&action=edit&redlink=1" class="new" title="Fluïdum (bladsy bestaan nie)">fluïdum</a> (eter) bestaan. </p><p>Die eter sou dan oral teenwoordig wees, in lugleegtes sowel as in stowwe, en die lig sou rimpels in die eter verteenwoordig. Die reglynige voortplanting, die weerkaatsing en die breking van lig het volgens Huygens met die van golwe in <a href="/wiki/Gas" title="Gas">gasse</a> en <a href="/wiki/Vloeistowwe" class="mw-redirect" title="Vloeistowwe">vloeistowwe</a> ooreengekom. Om sy teorie oor breking te staaf, moes hy aanvaar dat lig, in teenstelling met Newton se opvatting, vinniger in lug (yl) as in water of <a href="/wiki/Glas" title="Glas">glas</a> beweeg. <a href="/wiki/Pierre_de_Fermat" title="Pierre de Fermat">Pierre de Fermat</a> (1601-1665) het ook probeer om die gedrag van lig te verklaar en tot die gevolgtrekking gekom dat lig stadiger beweeg namate die media digter word. </p><p>Eers omstreeks die middel van die vorige eeu het <a href="/w/index.php?title=Armand_Fizeau&action=edit&redlink=1" class="new" title="Armand Fizeau (bladsy bestaan nie)">Armand Fizeau</a> (1819-1896) daarin geslaag om die snelheid van lig in water en lug te bereken, en kon hy bevestig dat dit in stryd was met die opvatting van Newton. Teen die tyd is Huygens se golfteorie oor lig egter reeds sterk aangehang, en is daar begin met die verbetering en die uitbouing daarvan. <a href="/wiki/Thomas_Young" title="Thomas Young">Thomas Young</a> (1773-1829) het byvoorbeeld die gedagte geopper dat wanneer die styging van een golf die daling in 'n ander golf sou tref, die golwe mekaar sou teenwerk en die resultaat in 'n egalige gebied in die eter nie meer as lig waargeneem sou word nie. </p><p>Lig plus lig sou dan in der waarheid duisternis veroorsaak. Die verskynsel, bekend as <a href="/w/index.php?title=Interferensie&action=edit&redlink=1" class="new" title="Interferensie (bladsy bestaan nie)">interferensie</a>, is deur Young met behulp van eksperimente geïllustreer. In die stadium is daar van die veronderstelling uitgegaan dat lig uit longitudinale golwe, dit wil sê uit afwisselende verdigtings en verdunnings van die eter, bestaan. <a href="/w/index.php?title=Etienne_Louis_Malus&action=edit&redlink=1" class="new" title="Etienne Louis Malus (bladsy bestaan nie)">Etienne Louis Malus</a> (1775-1812) het egter in 1809 vasgestel dat wanneer 'n ligbundel deur 'n bepaalde optiese stelsel (polariseerder) gestuur word, dit besondere eienskappe vertoon, deur byvoorbeeld uit sekere rigtings deur die stelsel te gaan en nie uit ander rigtings nie. </p><p>Thomas Young het op grond hiervan in 1817 tot die gevolgtrekking gekom dat die eienskappe van gepolariseerde lig slegs verklaar kon word deur aan te neem dat die liggolwe of -trillings transversaal, dit wil sê dwars, op die voortplantingsrigting voortgeplant word. Oor die algemeen sou lig dan in enige rigting dwars op die voortplantingsrigting beweeg en die polariseerder, soos 'n snit, net die lig wat in 'n sekere rigting beweeg, deurlaat. Aangesien slegs longitudinale golwe deur 'n gas kan beweeg, het daar toe verwarring ontstaan oor hoe lig dan eintlik voortgeplant word. </p><p>'n Aanvaarbare verklaring vir die gedrag van lig kon eers gegee word met die ontwikkeling van die teorie van <a href="/wiki/Elektromagnetisme" title="Elektromagnetisme">elektromagnetisme</a>. In 1862 het <a href="/wiki/James_Clerk_Maxwell" title="James Clerk Maxwell">James Clerk Maxwell</a> (1831-1879) sy teorie oor elektromagnetiese golwe geformuleer, waaruit dit duidelik geword het dat sowel <a href="/wiki/Elektrisiteit" title="Elektrisiteit">elektriese</a> as <a href="/wiki/Magnetisme" title="Magnetisme">magnetiese velde</a> met golwe geassosieer kan word. In 1865 het Maxwell die afleiding gemaak dat 'n kombinasie van elektriese en magnetiese velde as transversale trillingsverskynsels in die ruimte voortgeplant word, met ŉ snelheid wat met die van lig ooreenkom. </p><p>So het hy tot die gevolgtrekking gekom dat lig ook 'n vorm van elektromagnetiese straling is. Die golflengte van liggolwe blyk tussen 400 en 800 nm te wees (I nm=10<sup>- 9</sup> m). Dit was egter nog moeilik om te bepaal waaraan die energie van lig toegeskryf kon word, en daar is van die veronderstelling uitgegaan dat ligenergie eweredig was aan die sterkte van die elektriese en magnetiese velde. </p><p>In 1905 het <a href="/wiki/Albert_Einstein" title="Albert Einstein">Albert Einstein</a> (1879-1955), na aanleiding van eksperimente oor die fotoëlektriese uitwerking van lig, op die moontlikheid gewys dat afgesien van elektromagnetiese golwe, lig ook uit klein golfpakkies, oftewel fotone bestaan. <a href="/wiki/Foton" title="Foton">Fotone</a> blyk die kleinste moontlike ligeenhede te wees met energie eweredig aan die golflengte en snelheid van lig. Die gedrag van fotone herinner aan die deeltjieteorie van Newton, hoewel Newton deeltjies met voortplanting en nie met energie in verband gebring het nie. Fotone is dus alleen van betekenis by die oordrag van energie wanneer 'n ligpuls ŉ deeltjie tref, terwyl golwe op al die voortplantingsverskynsels betrekking het. Hierdie golf/deeltjie-aard van lig bring mee dat daar van die dubbelaard van lig gepraat word. </p> <div class="mw-heading mw-heading2"><h2 id="Snelheid_van_lig">Snelheid van lig</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Lig&veaction=edit&section=2" title="Wysig afdeling: Snelheid van lig" class="mw-editsection-visualeditor"><span>wysig</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Lig&action=edit&section=2" title="Edit section's source code: Snelheid van lig"><span>wysig bron</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Aan die begin van die 17e eeu was daar meningsverskil oor wat die snelheid van lig sou wees. <a href="/wiki/Ren%C3%A9_Descartes" title="René Descartes">Rene Descartes</a> (1596-1650) het byvoorbeeld gemeen dat lig oneindig vinnig beweeg, terwyl <a href="/wiki/Galileo_Galilei" title="Galileo Galilei">Galileo Galilei</a> die teenoorgestelde geglo het. <a href="/w/index.php?title=Olaus_R%D3%A7mer&action=edit&redlink=1" class="new" title="Olaus Rӧmer (bladsy bestaan nie)">Olaus Rӧmer</a> (1644-1710) het bevestig dat hoewel geweldig vinnig, lig nie oneindig vinnig beweeg nie, en 'n redelik goeie skatting van die snelheid van lig gemaak deur die verduistering van een van Jupiter se mane dop te hou. </p><p>Die Jupiter-maan het 'n onreëlmatige verduisteringspatroon gehad, en volgens Rӧmer sou dit nie waarneembaar gewees het as lig oneindig vinnig beweeg het nie. Deur die afwykings (in <a href="/wiki/Tyd" title="Tyd">tyd</a>) van die Jupiter-maan met die afstand tussen die aarde en Jupiter in verband te bring, het hy die snelheid van lig op 'n derde van die werklike snelheid geskat.
