Obj 3.15- Recall that the angle of Incidence equals the angle of reflection

- Light waves are transverse.
- Light always travel in straight lines.

- Light can be diffracted, refracted and reflected.

We see things in two ways-

Either if they are a light source or if light reflects off them.


This diagram shows that:

Angle of incidence = Angle of reflection

Opaque materials do not let light through but transparent materials do let light through.
