Question

The intensity of scattered light varies inversely as the power of wavelength of incident light where a. n=2 , b. n=1 , c. n=4 , d. n= -4
​

Answer 1

Answer:

Rayleigh scattering is the (dominantly) elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. The amount of scattering is inversely proportional to the fourth power of the wavelength.

Answer 2

Answer to the given question

Explanation:

• Intensity of the scattered-light is inversely-proportional as the fourth-power of wavelength.
• Intensity is a measure of average power associated with waves & is measured as power per unit area.

• Rayleigh-scattering is elastic (dominantly) scattering of light or any other electromagnetic-radiation by particles or molecules which is smaller than wavelength of electromagnetic-radiation.

• This relation exists when size or shape of air-molecules is smaller than wavelength of light-incident.

• Option c is correct. (n = 4)
