Description
This is a simulation of the superposition of two transverse waves travelling in opposite directions in the same medium. The magenta wave at the bottom is the sum of the red and blue waves. Use the sliders to adjust the wave speed, the amplitude of each wave, and the wavelength of each wave. Step through the animation with the Step Animation button or press the animation button in the lower left corner to run the animation. Use the check boxes to show opt hide the grid, as well as change the direction of the red wave.

A standing wave occurs when incoming and reflected waves interfere with each other. It produces a wave pattern that appears to be stationary.
Nodes are locations where particles of the medium appear to be at rest. And, antinodes are locations where particles of medium move with the greatest speed.
In musical instruments, the fundamental frequency is the frequency that produces the simplest standing wave. In the case of strings, the shorter the string, the higher the frequency.

standing wave between two fixed ends: have two nodes at ends.

standing wave between fixed-free ends: have one node and one antinode.

standing wave between two free ends: have two antinodes at ends.

This is a visual simulation of the reflection of a wave pulse. Use the check boxes choose between a fixed end (bouncing off a more rigid medium) or a free end (bouncing off a less rigid medium). Use the other check boxes to show or hide the undisturbed incident and reflected waves, so that you can see how their superposition causes the shape of the actual wave.

String instrument

Since string instruments are tied on both sides of the string, the string's end becomes the vibration's knot. When the string is bounced or rubbed with a bow, the string vibrates and makes a sound. String instruments produce lower sounds when having a longer and heavier string.

The reason small instruments are cover the higher range is that the shorter the string, the higher the sound.
