- - - - Total internal reflection
      - Less dense > denser >>> towards normal
      - Denser > less dense >>> away from normal

        Incident ray The ray of light that hits the surface.
        
        Reflected ray The ray of light that reflects from the surface.
        
        Normal Perpendicular to the surface at the point of incidence.
        
        Angle of incidence (i) Angle between the incident ray and the normal.
        
        Angle of reflection (r) Angle between the normal and the reflected ray.
    - - The sun is our main source of light.
      - We can see an object only if light is reflected from it.
      - All organisms need light to survive.
