Question

what is the correct reason for blinking or flickering of stars? explain it .a) the blasts in the stars. b) absorption of star light by the atmosphere. c) motion of the stars. d) changing refractive index of gases in the atmosphere. ​

Answer 1

option d is the correct answer because the atmosphere is a very dense layer which causes refraction and the light of the star will bend towards us and we can see it it is also because of the difference in the apparent position and the position we think it is in.
