Question

THINK ZONE A ray of light travels from medium 1 of refractive index 1.44 to medium 2 of refractive index 1.2 and then finally emerges out from medium 3 of refractive index 1.67. What can you say about the bending of the refracted ray while crossing each media? 9​

Answer 1

Answer:

Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. As per Snell's law and the given information, 

n1sin i = n2sin r 

∴ sin rsin i = n1n2

Answer 2

Answer:

Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. As per Snell's law and the given information,
