Standing Wave Diagrams 1 - Both Ends Fixed. Standing waves are usually shown on a printed page as a static, or motionless, diagram.
Of course, like all waves, they are dynamic; they have a motion. This interactive animation will help you understand how a static standing wave diagram is meant to convey the true motions of the standing wave. To understand how to use this applet do the following: Check the '1st' harmonic radio button. Check the 'Wave' checkbox, uncheck the 'Envelope' checkbox. You will see a moving yellow string. What you are looking at is the true motion of a string fixed at both ends and vibrating in its fundamental mode, or its first harmonic.
Again, a static diagram representing a standing wave will usually only show the envelope of the vibration. Below are several static diagrams of standing waves for a medium fixed at both ends, along with the names for each vibration and a count of the antinodes and nodes for each vibration. Custom Search.
