A ray of light is incident on a medium at an angle i. It is found that the reflected ray is at right angles to the refracted ray . The refractive index of the medium is given by

A ray of light is incident on a transparent medium at polarizing angle. What is the angle between the reflected ray and the refracted ray .

A ray of light is incident on a medium at polarising angle .What is the angle betweeen the relfected and refracted rays?

If a ray of light is incident on a reflecting medium at the polarising angle, prove that the reflected and the refracted rays are at 90^(@) to each other.

A ray of light is incident at an angle of incidence 45^@ on an equilateral prism and emerge at an angle 45^@ then the refractive index of the medium of the prism is:

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?

A ray of light incidents on a refracting surface at 30^(@) with the surface . If the angle of refraction is 45^(@) refractive index of the medium is
