Light | A form of energy that travels at 3*10^8 m s^-1 |
Types of light beams | Diverging, converging, parallel |
Reflection | The bouncing of light off an object |
Types of reflection | Diffuse and regular |
Laws of reflection | 1: The incident ray, point of incidence, the normal and the reflected ray all lie in the same plane. 2: The angle of incidence is equal to the angle of refraction |
Virtual image | An image formed by the apparent intersection of rays. |
Parallax | The apparent movement of one object relative to another |
