Question:

Name the mirror used for the following situations :

(a) Headlight of a car

(b) Side mirror/ rear mirror of a vehicle

(c) Solar furnace

Explain your answers.

Answer:

  • A concave mirror is used in the headlight of a car. The reason is that it is a good reflector and produces a parallel beam of light.
  • A convex mirror is used for side/rear view in a vehicle because it helps the driver to view large areas of the traffic behind him and he can easily detect the vehicle coming or running behind him.
  • A concave mirror is used in the solar furnace, because it focuses the rays of the sun and puts them on the furnace, due to which the furnace receives more heat.
