Diffraction patterns
Diffraction patterns are the unique, often colorful patterns created when waves, such as light or sound, encounter an obstacle or opening. As the waves pass around or through the edges, they bend and spread out. This bending creates areas of constructive interference (where waves amplify each other) and destructive interference (where they cancel out). The result is a series of light and dark spots or bands, which can reveal information about the shape and size of the obstacle or opening. These patterns are essential in fields like optics, acoustics, and even in analyzing materials at a microscopic level.

Diffraction patterns are visual arrangements of light or other waves that occur when they encounter obstacles or openings. When waves pass through narrow slits or around edges, they bend and spread out, creating interference patterns of bright and dark areas. This phenomenon can be observed in many contexts, such as water waves rippling around a barrier or light waves striking a slit. Typically seen in experiments with lasers or when sunlight passes through a small gap, diffraction patterns reveal information about the wave nature of light, illustrating how waves can interact with their environment in complex ways.
