If there is no Sun, the colour of the sky would be ________

A. Orange

B. Blue

C. Yellow

D. Black

Answer: Option D

Solution(By Examveda Team)

The sky appears blue because the sunlight is scattered by the gas molecules in the atmosphere - a phenomenon known as Rayleigh scattering - named after the discoverer - a British physicist who also discovered Argon - Lord Rayleigh (1842-1919). So, if there was no atmosphere, the sky would appear black.
