Question

Twinkling of stars is due to atmospheric

Options

• dispersion of light by water droplets

• refraction of light by different layers of varying refractive indices

• scattering of light by dust particles

• internal reflection of light by clouds

Answer 1

refraction of light by different layers of varying refractive indices

Explanation -

Due to the refraction of light by different layers of varying refractive indices, the apparent position of the source of light keeps on changing.
Due to this, stars appear to twinkle.
