Give two examples of the effect of atmospheric a refraction on a small scale in local environment.
Explain how twinkling of stars is an effect of atmospheric conditions on refraction of light.

An atmosphere :
We know that light refracts (or bends) when it goes from one medium to another. Now, the atmosphere contains only air. Then how does light get refracted on passing through only air in the atmosphere ?
What is the correct reason for blinking // flickering of stars ? Explain it. a. The blasts in the stars. b. Absorption of star light by the atmosphere. c. Motion of the stars. d. Changing refractive index of gases in the atmosphere.
