State Brewster's law . Show that the reflected and refracted rays are normal to each other at the polarising angle of incidence.

If a ray of light in a denser medium strikes a rarer medium at an angle of incidence i , the angle of reflection and refraction are respectively r and r', if the reflected and refracted rays are at right angles to each other, the critical angle for the given pair of media is

A ray of light is incident on a transparent glass slab of refractive index 1.62. If the reflected and refracted rays are mutually perpendicular, what is the angle of incidence ?

A ray of light enters from a rarer to a denser medium. The angle of incidence is I . Then the reflected and refracted rays are mutually perpendicular to each other . The critical angle for the pair of media is

A ray of light strikes a glass plate at an angle of 60^@ . If the reflected and refracted rays are perpendicular to each other, the index of refraction of glass is

Light is incident on a glass plate at an angle of 60^@ . The reflected and refracted rays are mutually perpendicular to each other. The refractive index of the plate is

State the laws of reflection.

From the Brewsters law it follows that the angle of polarisation depends on :

From the Brewsters law it follows that the angle of polarisation depends on :
