Scattering of light - when the white light is passes through a tiny particals the particles starts scattering different colors. This phenomenon is called scattering of light When the white light passes through a prism it's scattered into seven different colors this phenomenon is called dispersion of light

Scattering is the process in which an incident beam of light is redirected in many different directions when it interacts with a particle of matter...when sunlight strikes atoms in our atmosphere, the light is redirected in many directions...in fact, the blue light is scattered over greater angles than the red light causing the appearance of the blue daylight sky

dispersion is the process in which different wavelengths of light travel at different speeds when moving through a substance. all wavelengths of light travel at the same speed (what we call the speed of light) when traveling in a vacuum, but different wavelengths travel at different speeds through denser substances when light passes through a prism, different wavelengths travel at different speeds, and therefore refract (bend) at different amounts...this is why prisms can separate light into its component wavelengths

The splitting of white lights into its seven constituents colour is known as dispersion of light...
