A vertical ray of light strikes the horizontal surface of some water:

(a) What is the angle of incidence?

(b) What is the angle of refraction?

A ray of light passes from a medium X to another medium Y. No refraction of light occurs if the ray of light hits the boundary of medium Y at an angle of:

Which of the following diagrams shows the ray of light refracted correctly?

How is the reflection of light ray from a plane mirror different from the refraction of light ray as it enters a block of glass?

How does the light have to enter the glass?

(a) To produce a large amount of bending?

(b) For no refraction to happen?
