Answer 2

Scattering

Given:

Wavelength of 1st light source A is X.

Wavelength of 1st light source B is Y.

To find:

Ratio of light scattered from A and B.

Explanation:

Scattering:

It is a phenomenon when a beam of light falls on a rough surface it is turned back in different directions.

Wavelength:

The distance between the two successive crests or troughs of the light wave is called wavelength.

Relation between scattering of light and wavelength:

Rayleigh scattering law states that the amount of scattering of light is inversely proportional to the fourth power of the wavelength, it can be written as,

$I=\frac{1}{\lambda^4}$

This implies for shorter wavelength, light is more likely to be scattered in comparison to longer wavelength, due to the inverse relationship between the two.

So, for this question,

Ratio of light scattered from A and B = $\sqrt[4]{\frac{B}{A} }$ .
