Question

6. Which optical phenomenon is responsible for the twinkling of stars?
A. Atmospheric reflection B. Atmospheric refraction C. Dispersion D. Scattering​

Answer 1

Answer:

A. Atmospheric reflection

Explanation:

The atmospheric refraction is responsible for the twinkling of stars. As the light from the stars enters the earth's atmosphere it suffers refraction and causes the twinkling.

Answer 2

B ) Atmospheric Refrection

◆ The twinkling of a star is due to atmospheric refraction of starlight.

◆ The starlight, on entering the earth's atmosphere, undergoes refraction continuously before it reaches the earth.

◆ The atmospheric refraction occurs in a medium of gradually changing refractive index.
