A ray of light is incident on a prism of refractive index `mu` and angle A at the angle of incidence `i_(1)` and emerges at the angle `i_(2)`. If the ray is incident on the prism at the angle `i_(2)`, calculate the deviation of the ray.

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.

A light ray is incident on one refraction face of a prism, of refractive angle A, at an angle of incidence, I and emerges from the opposite face, normally. If refractive index of the material of the prism be mu what will be the value of the angle of incidence?

When a ray of light is incident on a plane normally, then what is the value of angle of refractive?

A ray of light is incident on a reflecting surface making an angle 50^(@) with the surface. Due to reflection, the angle of deviation is

A ray of light is incident normally on a face of the prism of refracting angle 30^(@) and refractive index sqrt(2) . Calculate the angle of deviation in degree.

A ray of light is incident at an angle I on a glass slab of refractive index mu . The angle between reflected and refracted light is 90^(@) . Then the relationship between I and mu is

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.

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?
