An equilateral glass prism `(mu = 1.6)` is immersed in water `(mu = 1.33)`. Calculate the angle of deviation produced for a ray of light incident at `40^@` on one face of the prism.

An equilateral glass prism of refractive index 1.5 is immersed in water. Find the angle of deviation produced when a ray of light is incident at 42^(@) on one face of the prism. (Refractive index of water = 1.33)

A thin glass prism of mu = 1.5 is immersed in water of mu =1.33 . The ratio of deviation of the ray in water to that in air for the same prism is

A glass prism of angle 72^(@) and refractive index 1.66 is immersed in a liquid of mu = 1.33 . Calculate the angle of minimum deviation.

Light is incident from glass (mu = 1.50) to water (mu = 1.33) find the range of the angle of deviation for which there are two angles of incidence.

(i) A ray of light incident on face AB of an equilateral glass prism, shows minimum deviation of 30^(@) . Calculate the speed of the light through the prism. (ii) Find the angle of incidence at face AB so that the emergent ray grazes along the face AC.

For a glass prism (mu = sqrt(3)) the angle of minimum deviation is equal to the angle of the prism. Find the angle of the prism.

A ray of light passes from glass (mu_(g) = 1.52) to water (mu_(w) = 1.33) . What is the critical angle of incidence?

A prism is made of glass of unknown refractive index. A parallel beam of light is incident on a face of the prism. By rotating the prism, the minimum angle of deviation is measured to be 40^@ . What is the refractive index of the prism ? If the prism is placed in water (mu = 1.33) , predict the new angle of minimum deviation of the parallel beam. The refracting angle of prism is 60^@ .
