Scattering of light is most pronounced when the wavelength of light is:
AMuch longer than the particle size
BMuch shorter than the particle size (option)
CComparable to the size of the scattering particles
DEqual to the speed of light
Answer & Solution
Correct answer: C. Comparable to the size of the scattering particles
1. Rayleigh scattering peaks when wavelengths are similar to or smaller than the scatterer.
2. In the atmosphere, air molecules scatter short wavelengths (blue) more than long (red).
3. This is why the sky is blue and sunsets are red.
