A ray of light incident at the pole at angle `25^@` will be reflected at an angle `25^@`

A ray of light is incident at an angle of 60^(@) on one face of a prism of angle 30^(@) . The ray emerging out of the prism makes an angle of 30^(@) with the incident ray. The emergent ray is

A ray of light is incident on the surface of seperation of a medium at an angle 45^(@) and is refracted in the medium at an angle 30^(@) . What will be the velocity of light in the medium?

A ray of light incident at the ................... (focus/pole) is reflected at the same angle with the principal axis

A ray of light-is incident on glass at the polarising angle ip. Find the angle between the reflected and refracted rays.

A ray of light is incident at an angle i from denser to rare medium. The reflected and the refracted rays are mutually perpendicular. The angle of reflection and the angle of refraction are respectively r and r'. Then the critical angle will be:

A ray of light is incident at an angle of 60^@ on the face of a prism having refracting angle 30^@. The ray emerging out of the prism makes an angle 30^@ with the incident ray. Show that the emergent ray is perpendicular to the face through which it emerges.

A ray of light is incident at an angle of 60^@ on the face of a prism having refracting angle 30^@. The ray emerging out of the prism makes an angle 30^@ with the incident ray. Show that the emergent ray is perpendicular to the face through which it emerges.

A ray of light is incident at an angle of 30^(@) with the plane of a plane mirror. Find the angle of reflection.

On a plane mirror, a ray of light is incident at an angle of 30^@ with horizontal . To make the reflected ray vertical , at what angle with horizontal must a plane mirror be placed ?

Show that for a light ray incident at an angle i on getting reflected the angle of deviation is delta=pi-2i or pi +2i .
