Which phenomenon explains why the sky appears blue?

  • AScattering of blue light by atmospheric molecules
  • BReflection of ocean colour
  • CAbsorption of blue light by clouds
  • DRefraction through ice crystals
Permalink
Correct Answer: Option A — Scattering of blue light by atmospheric molecules
Explanation: The sky appears blue due to Rayleigh scattering where shorter blue wavelengths of sunlight are scattered more strongly by atmospheric gas molecules than longer wavelength red light.
