Light

1. Reflection

   • When light reaches a mirror, it reflects off the surface of the mirror:
     • -The incident ray is the light going towards the mirror.
       • -The reflected is the light coming away from the mirror
   • Ray diagram
     • The hatched vertical line represents the mirror
       • The dashed line is called the normal and is drawn at 90 degrees to the surface of the mirror
         • The angle of incidence is the angle between the normal and the incident ray
           • The angle of reflection is the angle between the normal and the reflected ray
             • The law of reflection states that the angle of incidence equals the angle of reflection, i = r. It works for any angle.

2. Refraction

3. Diffraction

4. Absorbtion

5. Transmission
