1. Standing Waves

2. 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.

3. The standing wave pattern shown below has 3 distinct lobes, which are called “anti-nodes”. It also has 4 regions called “nodes”.

4. Nodes are regions of zero displacement caused by total destructive interference. Anti-nodes are regions of maximum displacement caused by constructive interference.
