Thaum nws los txog rau lub teeb muaj feem xyuam rau cov looj tsom iav dub, peb hom teeb pom kev hauv qab no tseem ceeb:

Direct light - Direct light is the light from a light source (xws li lub hnub) uas hits koj ob lub qhov muag ncaj qha. Lub teeb ncaj qha ntau dhau tuaj yeem pom cov ntsiab lus ntawm koj ib puag ncig thiab ua rau nws nyuaj rau tsom koj lub qhov muag.
Reflected light - Reflected light feem ntau nyob rau hauv daim ntawv ntawm glare. Reflected light yog lub teeb reflected rov qab mus rau lub qhov muag los ntawm ib tug reflecting khoom. Zoo li lub teeb ncaj qha, lub teeb pom kev zoo ua rau nws nyuaj rau kev paub meej lossis saib ncaj qha ntawm ib qho khoom. Daus, dej, iav, thiab xuab zeb dawb yog tag nrho cov zoo reflectors.
Diffused light - Diffused teeb bounces tawm nyob rau hauv ntau cov lus qhia, thiaj li hais tias nws tsis tshwm sim kom muaj ib tug tshwj xeeb lub teeb. Ib qho piv txwv classic ntawm diffuse lub teeb yog lub ci ci hla lub nroog loj. Nws yog ib qho nyuaj rau pin down ib lub teeb ci rau nws. Thaum tsis muaj teeb pom kev ncaj qha, peb tseem tuaj yeem pom tej yam, uas yog credit ntawm diffuse lub teeb.
Cov looj tsom iav dub zoo tshem tawm cov kab hluav taws xob ultraviolet los ntawm cov spectrum, txo cov teeb pom kev ncaj qha thiab ua rau tib neeg nyiam, ntxiv rau kev tshem tawm lossis txo cov teeb pom kev zoo (nyob ntawm qhov chaw pom).
Ib qho txiaj ntsig zoo ntawm lub teeb yog polarization. Thaum pom ntawm qee qhov chaw, xws li dej, lub teeb yog polarized. Vim lub polarized xwm ntawm reflected lub teeb, polarized looj tsom iav dub tshem tawm lub teeb reflected los ntawm dej los yog zoo li reflective nto.
