उत्तर
Intensity of scattered light as a function of incident light wavelength `I ∝ 1/λ^4`
The wavelength of red light (8000 Å) is the greatest and red light scatters the least, while the wavelength of violet light (4000 Å) is the least and scatters the least.
Conditions: When this dependence holds, → the incident light's wavelength should be greater than the size of the air molecule or scattering particles.
