The angle formed between the reflected ray and the normal is ------.

The angle between the resultant contact force and the normal force exerted by a body on the other is called the angle of friction. Show that it lamda be the angle of friction and mu the coefficient of static friction. lamdaletan^-1mu .

A ray enters a glass sphere of refractive index mu = sqrt3 at an angle of incidence of 60^@ , a ray is reflected and refracted at the farther surface of the sphere. The angle between the reflected and refracted rays at this surface is

Incidant angle of a ray of light is 30^@ . The angle between the incident ray and the reflected ray is ______.

A light ray is incident on air-liquid interface at 45^@ and is refracted at 30^@. What is the refractive index of the liquud? For what angle of incidence will the angle between reflected ray and refracted ray be 90^@? (AS_(7))

The incident ray , the refracted ray of light and the normal to the refracting surface all lie in the different plane .

Diffrence between a reflection and a shadow.
