Rays of light fall on a glass slab (`mu`gtl)as shown in the figure. If `mu` at A is maximum and at b it is minimum, then what will happen to these rays?

A ray of light is incident on a parallel-sided glass slab as shown in the figure. The angle of refraction for this ray of light is likely to be :

A ray of light strikes a glass slab (R.l. = mu ) of finite thickness t. The emerging light is

A ray of light strikes a glass slab (R.l. = mu ) of finite thickness t. The emerging light is

A ray of light falls on a glass slab making an angle of 45^(@) with normal. The emergent ray makes the same angle with normal. It shows that

A ray of light is falling on a glass sphere of mu=sqrt(3) such that the incident ray and that the incident ray and the emergent ray, when produced, intersect at a point on the surface of the sphere. Find the value of angle of incidence.

A ray of light falls normally on a glass slab. Draw a diagram showing the path of the ray till it emerges out of the slab. What is the angle of incidence and angle of refraction at each surface of slab ?
