Solution:Concept: In this line, we are asked what light scattering is. Before knowing how light is dispersed, we must first comprehend what is meant by dispersion in order to reply to this question.
At the source of the light, everything about it is visible. Some of the light rays are absorbed by the medium's particles when they go from one medium, like air, to another, like a glass of water, and then they radiate in another direction. This process is referred to as light scattering.
Shorter wavelength and higher frequency lines scatter more as a result of the line's wavelike properties and how it interacts with a particle. With increasing line length, there is a higher chance that a line may contact a particle. Conversely, if wavelengths are longer, low frequency, they are straighter, and there are less chances to contact the particle, then there are often fewer opportunities.
The afternoon's multicoloured light bends due to light refraction and complete internal reflection. Sunlight's wavelength produces a range of colours depending on the direction. The morning sun's red colour and the blue of the sky are caused by Rayleigh scattering.
Consequently, choice is the right response (3) .
