Q: The blue colour of the sky is due to the:
  • A. Refraction of light
  • B. Scattering of light
  • C. Diffraction of light
  • D. Dispersion of light
Correct Answer: Option B - The blue colour of the sky is due to the Scattering of light. Sunlight reaches Earth’s atmosphere and is scattered in all directions by all the gases and particles in the air. Sunlight is white light which is the mix of seven colours namely violet, indigo, blue, green, yellow, orange, and red. We usually called it as VIBGYOR. The sunlight enters into the atmosphere and scattered. Blue light is scattered more than the other colours because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. If the atmosphere is not present then the sky is seen black in colour.
