Description :

This page is designed to help you understand “wave interference” that occurs when circular waves from two sources on a plane spread out and overlap.

● You can control the progression of time using buttons such as “>”. Pressing “0” will reset the time to zero.
● Check the checkboxes to show different displays.
● Check the “Conservation of Energy” checkbox when you want to display the amplitude of waves spreading across the plane more accurately.
(According to the law of conservation of energy, the energy density of a wave is inversely proportional to the distance from the source, so the amplitude is inversely proportional to the square root of the distance from the source.)
● In the “Components” display, you can move the superposition position by dragging the yellow dot with a PC pointer or sliding it with your finger on a tablet screen.
● You can control the frequency of the two superposed waves using the “f” slider. Initially, f = 100, and it can be adjusted within the range of 50 to 150.
● You can control the wave speed using the “v” slider. The initial value is 100, and it can be adjusted within the range of 50 to 150.
