Wave Interference Simulator
Two wave sources create constructive and destructive interference patterns.
Wavelength0 cm
Frequency0 Hz
Separation / λ0
Constructive lines0
Destructive lines0
What you can learn
- Where crests meet crests the waves add up: constructive interference.
- Where crests meet troughs they cancel: destructive interference.
- Higher frequency means shorter wavelength and more interference lines.
Frequently asked questions
What is constructive interference?
It happens when two waves are in phase and add together to make a larger wave. In the simulator these are the bright bands.
What is destructive interference?
It happens when waves are out of phase and cancel. In the simulator these are the dark bands where the water stays still.
