Light travels from one material with a refractive index (n1 = 1.5) to another material with refractive index (n2=1.7). If it strikes the surface at a 45° angle (also 45° to normal) What is the resulting angle (from the normal) in the second material?
PLZ help!
better review Snell's Law.
the ratio of sines is 1.5 : 1.7
