Energy Dissipation, Constructive and Destructive Interference

Wave Damping	Energy losses, called "damping," cause a wave to die away.
Constructive Interference	Constructive interference is demonstrated with single transverse pulses in a Slinky™.
Destructive Interference	Destructive interference is demonstrated with single transverse pulses in a Slinky™.

Important wave phenomena include energy dissipation (wave damping) and wave interference.
