definition of wavefront says that it is the combination of points in the same Phase but what do you mean by this statement explain in brief |

Answer» Wave front, imaginary surface representing corresponding points of awavethat vibrate in unison. When identical waves having a common origin travel through ahomogeneousmedium, the corresponding crests and troughs at any instant are in phase;i.e.,they have completed identical fractions of their cyclic motion, and any surface drawn through all the points of the samephasewillconstitutea wave front.TheFigureshows a spherical wave front (ws) for asoundwave spreading out from a point source and a plane wave front (wp) for a parallel beam of light, such as that emitted from a laser. Wave fronts for longitudinal and transverse waves may be surfaces of any configuration depending on the source, the medium, and the obstructions encountered.See alsoHuygens’ principle. |
