Chapter summary

Presentation: VPcjo

  • 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.
