Question

The blue colour of the clear sky is due to -; 1) Diffraction of light; 2) Dispersion of light; 3) Reflection of light; 4) Refraction of light

Answer 1

❀ $\large{ \underline\textbf{Answer - }}$


2) Dispersion of light


The blue colour of the clear sky is due to ${ \underline{\textbf{Dispersion of light}}}$

Answer 2

The correct answer is 2) Dispersion of light.

• Light with a high frequency scatters more, while light with a low frequency scatters less.

• Because violet, indigo, and blue have a high frequency, they disperse more in the sky, and all of those colours appear to be blue.

• Blue light is distributed across the sky as light passes through the atmosphere.

• As a result, it appears that the sky is blue.
