Standing Waves
(store energy)
Standing waves are an example of interference.
Standing waves are produced when two waves interfere which:
1. have the same amplitude
2. have the same wavelength
3. travel in opposite directions
A stationary wave pattern is produced.

NODES:
points of zero disturbance, destructive interference
ANTINODES:
points of maximum disturbance, constructive interference
Standing waves tend to store energy.
