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 incidence when light passes from vaccume to a medium of refractive index sqrt3 ? Angle of refraction is 30^@ . What is the angle of deviation in this case?

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.

A ray of light from air is incident on a sphere of refractive index sqrt(3) . If the angle of incidence is 60^(@) , calculate the angle between the incident ray and the emergent ray with the help of a diagram.

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

What is angle of refraction for perpendiculer incidence?

A ray of light passing through the medium of refractive index mu_(1) is incident on the surface of separation of another medium of refractive index mu_(2) . A part of the ray is reflected and another part is refracted. What should be the angle of incident so that reflected ray and the refracted ray are at right angles to each other?

A monochromatic ray of light is refracted from vacuum to a medium of refractive index mu . Determine the relation of the wavelengths of light in vacuum and in medium.

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?
