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. http://www.math.clemson.edu/~macaule/classes/f20_math8530/slides/math8530_lecture-6-04_h.pdf slowfast101
