How many nodes, not including the endpoints, are there in a standing wave that is two wavelengths long? Three wavelengths long?
Solution 28E Step 1 of 3: The node on the standing wave is the point on the wave where the amplitude of the wave is minimum. The opposite of the node is antinode, point on the wave where the amplitude is maximum. Step 2 of 3: For two wavelengths long wave, For two wavelengths long wave, we can see from the above figure. Excluding the endpoints, we have three minimum amplitude points on standing wave. Therefore number of nodes are three.
