Light scattering occurs in ________________.

Light scattering is a common phenomenon that occurs in colloidal solutions, which are solutions that contain tiny particles called colloids dispersed throughout a medium. 

When a beam of light is directed through a colloidal solution, the particles in the solution scatter the light in all directions. This phenomenon is known as Tyndall scattering. The amount of light scattering in a colloidal solution depends on various factors, such as the size and shape of the colloidal particles, their refractive index, and the wavelength of the incident light.
