a red ray and a violet ray are incident simultaneously on a glass slab. It is seen that the red ray is refracted but the violet ray is reflected. Explain the reason.

What is incident ray and reflected ray?

A ray of light incident on a medium at polarising angle.what will be the angle between the reflected and the refracted rays? Or, an unpolarised ray of light is incident on a rectangular glass block at Brewster's angle. What will be the angle between the reflected and the refracted rays?

When a light ray in air is incident on glass at 57^(@) , the reflected ray is completely polarised. If the same ray is incident on water at an angle theta , also the reflected ray is completely polarised. Then

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 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?
