Detailed Solution

Concept: Light scattering is influenced by the size of the dust particles and the wavelength of the light. The amount of scattering is inversely proportional to the wavelength's fourth power. Because violet and blue lights are scattered more than all other colours by the environment, the sky appears blue.

Because the Earth's atmosphere scatters the colours of the sun's white light, the sky appears blue.

The colours we see are the ones that survived the dispersion. This phenomenon is known as Rayleigh Scattering.

Rayleigh scattering has an inverse relationship with wavelength.

Colors with shorter wavelengths are more widely dispersed.

Violet and blue hues are dispersed throughout the environment and enter our eyes.
