Draw a labelled ray diagram of refraction of light through a parallel glass slab and triangular glass prism.

Q. Explain the refraction of light through a triangular glass prism using a labelled ray diagram. Hence, define the angle of deviation.

Q. Draw the path of a ray of light passing through a triangular glass prism. Label the angle of incidence and the angle of deviation in the ray-diagram.

Q.

Show by a diagram, the refraction of two light rays incident parallel to the prinicipal axis of a concave lens by treating it as a combination of a glass slab and two triangular glass prisms.

Q. Explain the refraction of light through a glass-slab with neat ray diagram.

Q. "A ray of light incident on a rectangular glass slab immersed in any medium emerges parallel to itself." Draw labelled ray diagram to justify the statement.
