What is the correct reason for blinking / 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.
d) Changing refractive index of gases in the atmosphere. Atmosphere is unstable due to changing density and temperature of air, hence refractive index of air keeps changing continuously. The position and brightness of the star keep changing continuously and the star appears to be twinkling.
