Vedclass · Answer

(C) The assertion is correct: The setting sun appears red because, at sunset, the sun's light travels a longer distance through the atmosphere. During this journey, most of the shorter wavelengths (blue and violet) are scattered away by atmospheric particles, leaving mostly the longer wavelengths (red) to reach our eyes.The reason is incorrect: According to Rayleigh's law of scattering, the intensity of scattered light $(I)$ is inversely proportional to the fourth power of its wavelength $(\lambda)$, i.e., $I \propto 1/\lambda^4$. Therefore, scattering is inversely proportional to the wavelength, not directly proportional.

Assertion : The setting sun appears to be red.
Reason : Scattering of light is directly proportional to the wavelength.

According to Rayleigh, when sunlight travels through the atmosphere, the amount of scattering is proportional to the $n^{\text{th}}$ power of the wavelength of light. Then the value of '$n$' is:

Frequencies of light incident on a system of scattering particles are in the ratio of $1: 2$. Then, the intensity of scattered light in a particular direction is
