INTERFERENCE OF WAVES

When two or more waves simultaneously and independently travel through the same medium at the same time, their effects are superpositioned. The result of that superposition is called interference. There are two types of interference: constructive and destructive.

Constructive interference occurs when the wave amplitudes reinforce each other, building a wave of even greater amplitude.




Destructive interference occurs when the wave amplitudes oppose each other, resulting in waves of reduced amplitude.
