Laser Interference

Laser interference occurs when two or more laser beams overlap and interact with each other. This interaction creates a pattern of bright and dark spots, known as an interference pattern. The bright spots result from the waves reinforcing each other (constructive interference), while the dark spots occur where they cancel each other out (destructive interference). This phenomenon showcases the wave nature of light and is used in various applications, including optical instruments and measurement techniques. By analyzing the patterns, scientists can gain insights into the properties of light and materials.
