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

The angle of deviation of a ray of light refracted through a parallel glass slab is

Under what condition the angle of deviation of a refracted ray through a prism will be minimum? '

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

What is the angle of deviation due to refraction of a ray of light incident perpendicularly on a refraction surface?

What do you mean by angle of deviation of a ray in case of refraction through a prism. Calculate the expression of the angle of deviation.

The angle of incidence for a ray of light at a refracting surface of a prism is 45^(@) . The angle of prism is 60^(@) . If the ray surface minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively, are:

What will be the angle of emergence of a ray of light through a prism for an angle of incidents 45^(@) ? The angle of the prism = 60^(@) , refractive index of the prism = sqrt2 .

The refractive index of the material of a prism is sqrt((3)/(2) and the refractive angle is 90^(@) . Calculate the angle of minimum deviation and the corresponding angle of incidence. Show that the limiting angle of incident for getting emergent ray is 45^(@) .

A ray of light is emerged from a prism of refracting angle 70^(@) . If the angle of refraction in the first refracting surface is 28^(@) , what is the angle of incidence at the second face?

A prism having refracting angle 4^(@) is placed in air Calculate the angle of deviation of a ray incident normally or nearly normally on it. The refractive index of the material of the prism =(3)/(2) .
