Explain the following terms : Angle of reflection Draw diagram/diagrams to show them.

Refractive index of the material of concave lens is mu . The lens is immersed inb a medium of refractive index mu_(1)(mu_(1)gtmu) . A parallel beam of light is incident on the lens. Draw a diagram to show the path of emergent rays.

The following diagram explains

A ray of light, after refracting through a concave lens, emerges parallel to the principal axis. Draw a ray diagram to show the incident ray and its corresponding emergent ray.

(a) Figure shows two isosceles right angled prisms A and B and the light rays incident on the prism A. complete the diagram to show the rays emerging out of the prism B. (b) State the principle used for completing the ray diagram in part (a) above.

Draw diagrams to show the formation of beats?
