Q. Mirage is due to:

  • (A) Unequal heating of different parts of the atmosphere
  • (B) Magnetic disturbances in the atmosphere
  • (C) Depletion of ozone layer in the atmosphere
  • (D) Equal heating of different parts of the atmosphere
Correct Answer - Option(A)
Explanation by: Mr. Dubey 
Mirages happen when the ground is very hot and the air is cool. The hot ground warms a layer of air just above the ground. When the light moves through the cold air and into the layer of hot air it is refracted (bent). A layer of very warm air near the ground refracts the light from the sky nearly into a U-shaped bend.
