1 Answer

Answer :

The surface on which light is incident and then reflected or refracted from that surface is called the perpendicular plane. The angle between the refracted ray and the perpendicular is called the angle of refraction . It is also called the angle of revolution.

A light ray travelling from denser to rarer medium at an angle of incidence more than critical angle of concerned media pair suffers. (1) reflection (2) refraction (3) diffraction (4) total internal reflection

Description : A light ray travelling from denser to rarer medium at an angle of incidence more than critical angle of concerned media pair suffers. (1) reflection (2) refraction (3) diffraction (4) total internal reflection

Last Answer : (4) total internal reflection Explanation: If the angle of incidence of light ray in the denser medium is greater than the critical angle of the concerned media pair, the light is not at all reflected in to the rarer medium but is totally reflected. This is known as 'total internal reflection'.
