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
