• 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.
