Which term describes scattering of light by particles that are small compared to its wavelength, with the amount of scattering dependent on the color of the light?

A) Rayleigh scattering

B) photon

C) laser

D) reflected light

Answer: A

Explanation: The scattering of light by particles that are small compared to its wavelength, with the amount of scattering dependent on the color of the light. Air molecules, for example, are 1,000 times smaller than visible light wavelengths and scatter blue light about four times more strongly than red light, which is why a clear sky looks blue.
