Question

Name the phenomenon responsible for twinkling of stars

Answer 1

The atmospheric refraction is the phenomenon that is the reason for the twinkling of stars.

The air that is present in the atmosphere is a dense fluid that is spread out over the region.

It is responsible for bending of the light beam that comes through the stars.

When it passed through the air then it suffers both the phenomenon before reaching earth.

Answer 2

Answer:

The phenomenon which is responsible for twinkling of stars is Atmospheric refraction.

Explanation:

• Atmoshperic  refraction is the deviation of electromagnetic wave and light of straight line when it passes through the atmosphere.
• It happens due to the velocity of light through air decreasing with increasing density.
• When the temperature gradients are strong,then atmospheric refraction becomes more severe
•  And when turbulence occurs in the air and atmosphere is heterogeneous  then refraction will not uniform.
• This lead to suboptimal condition seeing like twinkling of stars and  deformations of the Sun's shape soon before sunset and after sunrise.
