Establish the relation among deviation of a ray, angle of incidence and angle of refraction.

A ray of light is refracted from medium 1 to medium 2. Show that the ratio of the sine of the angle of incidence and the sine of the angle of refraction is equal to the ratio of velocity of light in medium 1 and that in medium 2.

Establish the relation of angle of deviation with angleA,i_1 and i_2

Show that for refraction of light through a parallel glass slab, the incident ray and the emergent ray are parallel to each other. Or, With the help of a diagram show how in case of a rectangular glass slab, when light is refracted by the two parallel faces of the slab, deviation between angle of incidence and angle of refractive is zero.

After reflection, angle of deviation is half of the angle of incidence. Find out the angle of incidence

If the refracting angle of a prism is A, the refractive index of its material is mu and the angle of deviation of a ray of light incident normally on the first refraction face is delta , then prove that mu = sin(A + delta)/(sinA).

Calculate the angle of deviation of a light ray refracting through a equilateral prism angle of incidence and refraction are 40^@ and 30^@ .

A light ray travels from vacuum into a medium of refractive index mu . If angle of incidence is twice the angle of refraction then calculate the angle of incidence.

What is the angle of deviation of a ray incident perpendicularly on a reflecting surface ?
