A ray of light is incident at an angle of `60^(@)` on one face of a prism which has refracting angle of `30^(@)` . The ray emerging out of the prism makes an angle of `30^(@)` with the incident ray. If the refractive index of the material of the prism is `mu=sqrt(a)` , find the value of a .

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 at an angle of 60^(@) on a prism whose refracting angle is 30^(@) . The ray emerging out of the prism when produced backward makes an angle of 30^(@) with the incident ray produced forward. Find the refractive index of the material of the prism.

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 one face of a 30^(@) prism . The emergent ray from the prism makes an angle of 30^(@) with the incident ray. The angle of emergence and refractive index of the material of the prism are-

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 and calculate the refractive index of the material of prism.

When light rays are incident on a prism at an angle of 45^(@) , the minimum deviation is obtained. If refractive index of the material of prism is sqrt(2) , then the angle of prism will be

A ray of light is incident at an angle of 60^(@) on the face of a prism with an angle of 60^(@) . Then the refractive index of the material of the prism is (the prism is in minimum deviation position)
