Standing Waves

Shows how incident and reflected waves at a rigid boundary can interfere to produce a standing wave.[br][br]You can change the frequency/wavelength, hide or show the incoming, outgoing and standing waves, and hide or show the positions of the nodes and antinodes.

Nodes

What is the spacing of the nodes?

[math]\lambda\slash2[/math] [math]\lambda\slash4[/math] [math]\lambda[/math]

Antinodes

What is the amplitude at the antinodes?

Not fixed. It changes with time Same as the incoming wave 2 x Amplitude of incoming wave

Relative phase at the nodes

What is the relative phase of the incident and reflected waves at the nodes?

90[sup]o[/sup] 0 180[sup]o[/sup]
