Understanding Light Wave Interference: Constructive and Destructive Effects
This animation illustrates how light waves interact through interference. It demonstrates constructive interference, where two waves in phase combine to create a new wave with increased amplitude, and destructive interference, where waves out of phase either partially cancel each other or completely negate each other. Observe how amplitude varies based on the phase relationship of the waves. Gain insight into the fascinating behavior of light waves thanks to Dr. Dan Russell from Kettering University and explore the principles behind wave interactions.

Constructive and Destructive Interference The graphic on the right shows two waves coming towards each other. The blue wave at the bottom shows the wave that forms when the top two waves meet. When does the new wave formed have the highest amplitude? When do the waves cancel each other out? Animation courtesy of Dr. Dan Russell, Kettering University
When two waves of identical wavelength are in phase, they form a new wave with an amplitude equal to the sum of their individual amplitudes (constructive interference). When two waves are of completely opposite phase, they either form a new wave of reduced amplitude (partial destructive interference) or cancel each other out (complete destructive interference).
