The document discusses different types of interactions between light and matter: 1. Reflection is when light bounces off surfaces at the same angle. 2. Refraction is when light changes direction as it passes from one medium to another due to the change in speed. 3. Dispersion is when light separates into its component wavelengths, causing the visible color spectrum. 4. Scattering is the irregular reflection of light in many directions by particles or objects in its path. 5. Diffraction is the bending of light around obstacles or the spreading out of light waves when they encounter obstacles.
