1 Wave Building Blocks Pulses

2 Definitions PULSE - a single vibratory disturbance
Transmits ENERGY but not MASS AMPLITUDE - height above equilibrium and directly related to ENERGY. MEDIUM - a continuum of particles of the same type that stores and releases energy. As a pulse travels in a medium it… DOES NOT LOSE SPEED LOSES AMPLITUDE (ENERGY)

3 Phenomenon #1 - Reflection
Fixed Point Floating Point before before after after

4 Changing Mediums Fast  Slow Slow  Fast
If a pulse changes mediums it… MAY CHANGE SPEED MAY CHANGE AMPLITUDE PARTLY REFLECTS before before after after

5 Phenomenon #2 - Interference
Constructive Destructive

6 End of PRACTICE

Reflection and Refraction.  When a wave moves from one medium into another (reaches a boundary) ◦ Speed of the wave changes  More dense  slower  less.
