Standing Waves
What is a standing wave?
A standing wave is the result of identical, periodic waves moving in opposite directions.
When reflected waves interfere with incident waves, a pattern results that appears to be stationary.
The standing wave pattern shown below has 3 distinct lobes, which are called “anti-nodes”. It
also has 4 regions called “nodes”.
Nodes are regions of zero displacement caused by total destructive interference.
Anti-nodes are regions of maximum displacement caused by constructive interference.
