Rayleigh region
WebRayleigh scattering, dispersion of electromagnetic radiation by particles that have a radius less than approximately 110 the wavelength of the radiation. The process has been named in honour of Lord Rayleigh, who in 1871 … WebAnswer: Earth's atmosphere is full of particles, small enough that you can't see them. When the sun rays enter the atmosphere they encounter these particles & molecules. This encounter leads to change in the direction of sun rays known as scattering. The light is made up of different wavelengths...
