why does the scattering of sunlight occur ? what are the benefits of the scattering of light?
Answers
Q)What causes scattering of sunlight?
ANS) when the particles causing the scattering are larger than the wavelengths of radiation in contact with them, then the light scatters.
The particles/molecules that scatter light are called scatterers and can
also include particles from human industries.
The small particles (molecules, tiny water droplets and dust particles) scatter photons the more, the shorter their wavelength is. Therefore, in the scattered light, the short wavelengths predominate, the sky appears blue, while direct sunlight is somewhat yellowish, or even reddish when the sun is very low.
Scattering of sunlight
Due to the presence of the atmosphere, sunlight scatters. Air particles reflect the sun's light. When it's scattered, it travels in diverse directions. The dispersion of light depends on the particle's size. Nitrogen molecules are more effective at scattering short-wavelength light.
The Earth's atmosphere contains particles and gases that scatter sunlight in all directions. Because blue light propagates as more minor, shorter waves, it is far more scattered than any other colour, which is why the sky is blue most of the time.
The benefits of the scattering of light:-
- It's utilised to figure out what's going on with crucial phenomena.
- It aids in the determination of molecular weight.
- It is crucial in the analysis of air pollution.
- It explains the phenomenon of dissemination.
- The light scattered by the particles in the atmosphere causes the sky to appear blue.
- The sky appears crimson during sunset and sunrise due to light scattering.
