Best Answer

Explanation

  • Rayleigh scattering of sunlight causes the clear sky to seem blue.
  • The sun's blue light is scattered more by the molecules in the air than it is by red light.
  • The size of the dust particles and the wavelength of the light affect light scattering.
  • The quantity of scattering is inversely proportional to the wavelength multiplied by the fourth power.
  • The sky appears blue because violet and blue sunlight are dispersed more than all other colours by the atmosphere.

Final Answer

The correct option is C i.e violet and blue lights get scattered more than lights of all other colours by the atmosphere.
