What is the difference between plane wave and spherical wave?
In particular, if the wave is propagating out of a point source, the fronts are spheres around the source (see next page). Such a wave is called spherical wave. The waves considered above are called plane wave because they propagate in the direction x and not in the directions y and z.
What do you mean by spherical wave?
"Spherical waves are waves in which the surfaces of common phase are spheres and the source. of waves is a central point." Consider an ideal point source of light. The radiation originating from it streams out radially, uniformly in all directions.
Under what conditions can a spherical wave front be regarded as a plane wave front explain?
Under what conditions can a spherical wave front be regarded as a a plane wave front? Explain. As a sphere increases in radius, sections of its surface approach a plane surface. A plane wave os a section of a spherical wave that has such a large radius that sections of it appear planer.
