stars twinkle at night due to the atmospheric refraction of stars light
when the light coming from the stars enters the earth atmosphere, it undergoes refraction due to the varying optical densities of air...... the continuously changing atmosphere refracts the light from from the stars by different amounts from one moment to next.........
laws of refraction are......
1. the incident ray, the refracted ray, and the normal and all are lie in the same plane
2.sine of angle of incidence by sine of angle of refraction is equal to the constant
