3 Dimensionell Våg   till applet    v = f ×  l 
Nedan finns en animation av en vågrörelse längs en yta.

You can adjust the wavelength, frequency, and amplitude of the wave by clicking on the drop down list in the upper left corner, and then selecting one of the choices which appear.

The slider on the left moves your viewpoint closer to or farther from the wave.

The sliders on the right and bottom rotate your viewpoint around the wave in various directions. Experiment with them and you will quickly catch on to their operation.


Since the velocity of a wave is equal to its frequency times its wavelength, you should notice that by increasing the wavelength while the frequency remains constant causes the wave to speed up. And, of course, decreasing the wavelength while the frequency remains constant causes the wave to slow down. Play with this using the following dynamic equation.

Velocity Equals Frequency Times Wavelength

Also, notice that in a like manner, with the wavelength remaining constant, increases in frequency requires that the wave travel faster. Decreases in frequency require that the wave travels more slowly. Again, use the following slider to see this mathematics.

Velocity Equals Frequency Times Wavelength

Be sure that you understand the intentions of this animation. It is not meant to behave like a sound wave or light wave. With those waves, when you change the wavelength the frequency changes in an inverse fashion so as to keep the velocity of the wave constant. And, consequentially, if you change the frequency of a sound or light wave, the wavelength will change so that the velocity keeps the same value.

This animation simply demonstrates several combinations of values for wavelength and frequency, and, therefore generates several possibilities for the velocity of the wave. There is no intention to keep the velocity of the wave constant, as is true with sound and light waves.
