<prompt> Bheka isigaba esingezansi bese uphendula umbuzo ngemuva kwalokho ngolimi olufanayo nesigaba: Isigaba: Kusukela ngo-1670 kuya ku-1672, uNewton wafundisa nge-optics. Ngalesi sikhathi waphenya ukuphazamiseka kokukhanya, ekhombisa ukuthi i-multicolored spectrum ekhiqizwa yi-prism ingahle ihlanganiswe kabusha ibe ukukhanya okumhlophe nge-lens kanye ne-prism yesibili. Izifundo zesimanje ziveze ukuthi ukuhlaziywa kukaNewton kanye nokuvuselelwa kokukhanya okumhlophe kukweleta i-alchemy ye-corpuscular.Wakhombisa ukuthi ukukhanya okumibala akuguquli izakhiwo zayo ngokuhlukanisa i-beam enemibala futhi ikhanye ezintweni ezahlukahlukene, nokuthi kungakhathalekile ukuthi kukhonjisiwe, kuhlakazekile noma kudlulisiwe, ukukhanya kuhlala kungumbala ofanayo. Ngakho-ke, wabona ukuthi umbala uwumphumela wezinto ezixhumana nokukhanya okuvele kunemibala kunokuzikhiqiza umbala ngokwabo. Lokhu kwaziwa ngokuthi yiNewtons theory of color Umbuzo: Umbala uvela kuphi?  <response>: izinto ezixhumana nokukhanya okuvele kunemibala
