A ray of of light passes symmetrically through a glass prism `(mu = 1.5)` of angle `60^@`. Calulate:
angle of incidence.

A ray of light passes from air to glass (mu = 1.5) at an angle of 30^@ .Calculate angle of refraction.

A ray of light passes through an equilateral glass prism,such that angle of incidence is equal to the angle of emergence.If the angle of emergence is 3//4 times the angle of prism,calculate the refractive index of the glass prism.

A ray of light passes through an equilateral glass prism, such that angle of incidence is equal to the angle of emergence. If the angle of emergence is 3//4 times angle of prism, calculate the refractive index of the glass prism.

Draw a ray diagram to show the refraction of light through a glass prism. Hence obtain the relation for the angle of deviation in terms of the angle of incidence, angle of emergence and the angle of the prism.

A ray of light is incident on the glass prism at an angle of 40^@ .Find the angle of emergence,if the angle of prism is 60^@ and refractive index.

A ray of light suffers minimum deviation,while passing through a prism of refractive index 1.5 and refracting angle 60^@ ,calculate the angle of deviation and angle fo incidence.

A ray of light passing through an equilateral traingular glass prism from air undergoes minimum deviation,when angle of incidence is 3//4 of the angle of prism.Clculate the speed of light in the prism.
