Summary:

• Scattering is a deflection of the light, absorption is an elimination of light, and extinction is the combination of the two for transmitted light.
• Extinction exponentially reduces the intensity of light of transmitted light (Beer’s Law).
• Extinction can lead to cast and form shadows.
• Rayleigh scattering is strong in the forward and backward directions, weak to the sides.
• Mie scattering is strongest in the forward direction and weakest in the backward.
• Multiple scattering makes diffuse beams.
