Mængden af spredende foreliggende afhænger polariserende egenskaber af en bestemt type partikel og kan variere afhængigt af de elementer, der er involveret. Mængden af spredning er afhængig af en række faktorer.

WebRayleigh-spredning, opkaldt efter Baron Rayleigh, er den form for spredning af lys som skabes af partikler der er mindre end lysets bølgelængde: Sådanne partikler spreder blåt og violet lys mere end rødt og gult, fordi blåt lys har kortere bølgelængde end rødt lys. Virkningen kan ses i gennemsigtige faste og flydende stoffer, men er mest udtalt i gasser. WebDen Raman-spredning, eller Raman er et optisk fænomen opdaget uafhængigt i 1928 af fysikere C. V. Raman og Leonid Mandelstam.Denne effekt består af en fotones uelastiske spredning, det vil sige det fysiske fænomen, hvormed et medium let kan ændre frekvensen af det lys, der cirkulerer i det.
