Q: Twinkling of stars occurs because:
  • A. change in the density of different layers of air causes change in Tyndall effect continuously
  • B. change in the density of different layers of air causes change in scattering intensity continuously
  • C. change in the density of different layers of air causes change in colour of the sky continuously
  • D. change in the density of different layers of air causes change in refractive index continuously
Correct Answer: Option D - Twinkling of stars occurs because change in the density of different layers of air causes change in refractive index continuously.
D. Twinkling of stars occurs because change in the density of different layers of air causes change in refractive index continuously.

Explanations:

Twinkling of stars occurs because change in the density of different layers of air causes change in refractive index continuously.
