Question

PLEASE PLEASE HELP ME PLEASE AND THANK YOU

Which statement is true about the amount of refraction of light waves as they pass through a material, or medium?

Depends on the temperature of the light wave
Decreases with an increase in density of medium
Increases with an increase in density of medium
Depends on the angle at which the wave strikes the medium

Answer 1

I think the answer is D. It depends on the angle at which the wave strikes the medium.

Answer 2

Depends on the angle at which the wave strikes the medium

Step-by-step explanation:

The process of bending of light when it moves from one medium to another is called refraction of light. There are two laws of refraction :

1. The incident ray, the refracted ray and the normal all lie in the same plane

2. The ratio of sine of angle of incidence to the sine of angle of refraction is constant. It can be written as :

`(sin\ i)/(sin\ r)=constant`

This constant is equal to the refractive index of the medium. The above equation is called Snell's law. It can also written as :

`(sin\ i)/(sin\ r)=(n_2)/(n_1)`

Where n₁ and n₂ are refractive indices of two mediums. So, it is clear that the amount of refraction of light waves as they pass through a medium depends on the angle at which the wave strikes the medium. Hence, the correct option is (d).
