- - - - All objects send light
        
        Non-lumunous
        
        Something that does not produce light but can reflect light
        
        Luminous
        
        Something that produces light
  - - - Rules of refraction
        
        The incident ray and refracted ray are on opposite sides of the normal
        
        The incident ray, refracted ray and the normal are in the the same plane
        
        Light bends towards the normal when the second medium is more dense/slower
        
        Light bends away from the normal when the light in the second medium is less dense/faster
  - - - Angle of incidence = angle of reflection
      - The incidnet ray, reflected ray and the normal lie on the same plane
    - - Reflection off a soft surface
    - - Reflection off a rough surface
- - - - Cause parallel light rays to come together
  - - - Cause parallel light rays to spread apart
