(b) refraction of light by different layers of varying refractive indices
[B] Refraction of light by different layers of varying refractive indices
As we know that, due to refraction of light by different layers of varying refractive indices, the apparent position of source of light keeps on changing where our atmosphere play a vital role. So, stars appear to Twinkle.
[B] Refraction of light by different layers of varying refractive indices
We must know that air have different layers which act as varying refractive indices and when light enters by different layers of the apparent position of source of light keeps on changing. It happens due to refraction of light. So, stars appear to twinkle.
