Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): Mie scattering depends on the size of the scatterers in relation to the wavelength of radiation being scattered.
Reason (R): Approximate particle size of Mie scatterer is 0.1 to 10 $\mu$m.
In light of the above statements, choose the correct answer from the options given below.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Hint:

Scattering comparison based on particle size (\(d\)) relative to wavelength (\(\lambda\)):
- Rayleigh: \(d \ll \lambda\) (gas molecules, causes blue sky).
- Mie: \(d \approx \lambda\) (dust, smoke, pollen, \(0.1\text{ to }10\text{ }\mu\text{m}\)).
- Non-selective: \(d \gg \lambda\) (water droplets in clouds, causes white clouds).

Answer 1

The Correct Option is A
