A wave front is the path that a wave would follow if it were propagated through a medium. A wave front is a collection of all the points in the medium that are affected by the wave.
According to Huygens' principle, the wave front of a wave traveling through a medium will remain constant and propagate in the same direction as the wave. This principle can be explained by the fact that the wave front is a continuous distribution of points in the medium, and it therefore cannot bend around obstacles.
An example of a wave front is a crest of a wave on the surface of a lake. The crest of the wave is a collection of all the points on the lake that are at the same height as the crest. The wave front is also a line of constant height, and it propagates in the same direction as the wave.
The Huygens' principle is a fundamental principle of optics, and it is used to explain a wide variety of optical phenomena, such as the formation of images on a screen, the diffraction of light, and the propagation of light through a medium
