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

Antinodes

What is the amplitude at the antinodes?

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

Relative phase at the nodes

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

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