The intensity of scattered light is related to its wavelength as :

1. I ∝ λ⁴
2. I ∝ λ²
3. I ∝ $\dfrac{1}{λ^4}$
4. I ∝ $\dfrac{1}{λ^2}$

I ∝ $\dfrac{1}{λ^4}$

Reason — Intensity of scattered light is found to be inversely proportional to the fourth power of the wavelength of light.

(i.e., I ∝ $\dfrac{1}{λ^4}$ ).
