Question

 In which condition is mirage seen? Give such one more example.

Answer 1

A mirage is usually seen:

• On hot days, especially in deserts or on tar roads
• When the ground is very hot, and the air just above it is warmer than the air higher up
• This temperature difference causes light to bend (refraction), creating the illusion of water

One more example:

The twinkling of stars is another example caused by refraction of light in the Earth’s atmosphere.
