Vedclass · Answer

(C) The Assertion is correct because clouds appear white due to the scattering of light by water droplets. The size of water droplets in clouds is much larger than the wavelength of visible light. According to the theory of scattering, when the size of the scattering particle $(a)$ is much larger than the wavelength of light $(\lambda)$, i.e., $a \gg \lambda$, the scattering is independent of the wavelength. Since all wavelengths of visible light are scattered equally, the combined effect is perceived as white light. Diffraction is a phenomenon that occurs when light encounters an obstacle or aperture of a size comparable to its wavelength. Since cloud particles are much larger than the wavelength of light, they do not cause significant diffraction of visible light. Therefore, the Reason is incorrect.

Assertion: The clouds in the sky generally appear to be whitish.
Reason: Diffraction due to clouds is efficient in equal measure at all wavelengths.
