Identify the locations that remain always fixed (these are known as nodes) and the locations that oscillate most strongly (these are known as anti-nodes). Verify that the principle of superposition is accurate at these points.
With the wave reflecting from a free end in the simulation, click on Start, wait until the wave returns to its point of origin, and observe the new standing wave. What is different about it?
Shown at the bottom of the page are three different standing waves that can be formed a string or spring, like the one in the experiment. Suppose you have such a string with length L and that both ends are fixed.
For each sketch, determine the number of wavelengths that fit on the string. Use your answer to determine the wavelength \(\lambda\) in terms of the length of the string \(L\) and indicate it on your sketch.
