Superposition of Waves
Standing Wave Resonance in Tubes and on Strings
Standing Waves occur when two waves with the same wavelength, are traveling in opposite directions. If the system that contains the waves is of a certain size, a resonance occurs and the standing waves become more pronounced.
General Two Source Interference
When two waves enter the same space at the same time they can interfere in a such a way to cause a larger effect called constructive interference. They can also interfere in such a way to create a smaller effect called destructive interference. Light behaves like a wave and displays these light and dark inference patterns when setup in a clever way.
