WebThis phenomenon is termed a scattering of light. The intensity of scattered light depends on the size of the particles and the wavelength of the light. Shorter wavelength and high-frequency scatter more due to the waviness of the line and its intersection with a particle. The wavier the line, the more the chance it intersects with a particle.
