Ray Optics and ...

Two beams of red and violet colours are made to pass separately through a prism (angle of the prism is 60^o). In the position of minimum deviation, the angle of refraction will be:

A ray of light passes through an equilateral prism (refractive index 1.5) such that angle of incidence is equal to angle of emergence and the latter is equal to 3/4th of the angle of prism. The angle of deviation is

A ray is incident at an angle of incidence i on one surface of prism of small angle A and emerges normally from the opposite surface. If the refractive index of the material of the prism is μ, the angle of incidence is nearly equal to

The angle of minimum deviation for prism of angle π/3 is π/6, if the velocity of light in vacuum is 3 × 10⁸ ms⁻¹, then the velocity of light in material of the prism is

For a glass prism (μ = √3) the angle of minimum deviation is equal to the angle of the prism. The angle of the prism is
