vågstrålar
Vågstrålar, also known as wave rays or wavefronts, are a fundamental concept in the study of wave propagation, particularly in optics and acoustics. They represent the locus of points in space where the wavefronts of a propagating wave are located at a given instant in time. In other words, a vågstråle is a line or surface that connects all points that are at the same phase of the wave cycle.
In optics, vågstrålar are used to describe the direction of light propagation. They are perpendicular to the
Vågstrålar are essential in understanding phenomena such as reflection, refraction, and diffraction. When a wave encounters
Vågstrålar are also used in the design and analysis of optical systems, such as lenses and mirrors,
