diffraction theory
Diffraction theory refers to the behavior of waves, such as light and sound, as they encounter obstacles or openings. When waves pass through a narrow slit or around edges, they bend and spread out rather than traveling in straight lines. This creates patterns of light and dark spots or changes in sound intensity, depending on the wave. Diffraction is why we can hear someone speaking around a corner or see patterns in laser light. The extent of diffraction depends on the size of the obstacle or opening relative to the wavelength of the wave.

Diffraction theory describes how waves, such as sound or light, bend and spread when they encounter obstacles or pass through small openings. Instead of traveling in straight lines, the waves create patterns of interference, leading to areas of increased or decreased intensity. This phenomenon explains various everyday occurrences, like the spreading of sound around a corner or the rainbow effects seen when light passes through a small slit. Overall, diffraction highlights the wave nature of light and sound, illustrating how they interact with their environment in complex and fascinating ways.
