In a plane mirror if a ray of light reflects at `35^@` angle then what will be the value of incident angle?

If a ray of lights strikes a mirror perpendicularly what will be the value of reflected angle?

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

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?

If ray of light falls on a mirror at 30^@ angle the reflected angle becomes_______

At what angle does a ray of light remain incilned to the wavefront ?

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?

Two plane mirrors are inclined to each other at an angle theta .A ray of light is reflected first at one mirror and then at the other . The total deviation of the ray is

A light ray is incident on a rarer medium from a denser medium. The velocity of light in rarer medium is double its value in denser medium. For total internal reflection what should be the value of the critical angle?
