Huygens' principle
Huygens' principle is a concept in wave theory that suggests every point on a wavefront can be seen as a source of new waves. When a wave moves, each point on this front emits smaller waves, and together, these create a new wavefront. This idea helps explain how waves, like light or sound, spread and interact with obstacles. Essentially, it allows us to understand phenomena like reflection, refraction, and diffraction by depicting wave behavior as a series of overlapping waves emerging from various points.

Huygens' Principle is a concept in wave theory that explains how waves, like light or sound, propagate. It states that every point on a wavefront can be considered a source of new waves, called "wavelets." As these wavelets spread out, they combine to form a new wavefront. This principle helps us understand how waves travel, bend, and interfere with one another. Essentially, Huygens' Principle illustrates that waves are not just lines but can be thought of as a continuous series of sources generating new waves in all directions.
