Chapter summary
-
A medium is the substance or material in which a pulse will move.
-
A pulse is a single disturbance that moves through a medium.
-
The amplitude of a pulse is the maximum disturbance or distance the medium is displaced from its equilibrium position (rest).
-
Pulse speed is the distance a pulse travels per unit time.
-
Constructive interference is when two pulses meet and result in a bigger pulse.
-
Destructive interference is when two pulses meet and and result in a smaller pulse.
