(a) With the help of labelled ray diagram show the path followed by a narrow beam of monochromatic light when it passes through a glass prism.
(b) What would happen if this beam is replaced by a narrow beam of white light?
(The one answer it first will be followed by me.)

Answer:
White light can be split up into spectrum of these colours using a prism, a triangular block of glass. ... Light is refracted when it enters the prism, and each colour is refracted by some amount. Thus the rays of each colour emerge along different paths and thus become distinct.

The path of the light followed by a narrow beam of monochromatic light when it passes through the glass prism is given below.
Explanation:
- If a narrow beam of light is replaced by a white light then there will be splitting of the light into the seven colours which are present in the white light.
- This is due to the phenomenon of change in the refractive index of air and glass. In there will be different deviation for different rays of light. In addition to this there will be also nonunion of the seven colours after it has moved out of the prism.
