Stars twinkle at night give reasonno spamfoll.ow me​

Answer»

In the atmosphere, there are DIFFERENT layers of air with different refractive INDICES which KEEP on changing.When we observe the stars through this air the light coming from them refract randomly so that the intensity of light varies due to which the apparent position of the star fluctuates.When more light reaches our eyes the star is seen bright and when less light reaches our eyes, the star is seen dim.Thus, due to change in refractive index of atmosphere, stars appear twinkling at night. PLS mark me as BRAINLIEST!!!!
