Wave Building Blocks 5.1.2 Pulses

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)

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

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

Phenomenon #2 - Interference Constructive Destructive
