Rayleigh effect
WebThe Tyndall effect is caused by the scattering of light by colloidal particles. The phenomenon occurs when a fine beam of sunlight enters a room, filled with smoke, through a small aperture. As a result, light scattering makes the particles visible. When sunlight penetrates through a dense forest canopy, the Tyndall effect is seen.

This effect is strongly amplitude dependent and is poorly represented by Rayleigh damping. The … WebThe Raman effect is a relatively weak effect, in comparison to the Rayleigh effect. Less than 1% of scattered photons demonstrate the Raman effect compared to over 99% which exhibit the Rayleigh effect (4).Of those photons that are Raman scattered, the amount of Stokes scattering is greater than the amount of anti-Stokes scattering.
