Wave Behavior/ Phenomena

  1. Reflection: Wave reflects off of a surface at the same angle.

Law of reflection

Examples

Reflectors

don’t exactly meet in the center, but very close

        focuses exactly at one point

Why?

        the wave begins to travel at different speeds at different times

Example: Both sound and light waves travel faster through warmer

  1. Interference
