WebCylindrical wavefront: This is formed when the source of light is a line source. Huygen’s principle One major concept that you need to understand for the reflection and refraction of plane waves at a plane surface is Huygen’s Principle. In 1670, Christian Huygen came up with a theory that explained how waves propagated. A wavefront is an imaginary surface representing corresponding points of a wave that vibrate in unison. A wavefront is the set of all locations in a medium where the wave is at the same phase. This could be where all the crests are, where all the troughs are, or any phase in between. Wavefronts are useful … See more The path followed by the particles emanating from a source determines the different types of wavefronts.
