Defined wavefront. what is the spherical structure of wavefront.?
Answers
Answer:
A wavefront is a surface over which an optical wave has a constant phase. For example, When a stone is dropped in a still water, waves spread out along the surface of water in all directions with same velocity. Every particle on the surface vibrates. ... emits a spherical wave front

In most real cases, however, a wave originating at some source does not move in a straight line but expands in a series of spherical wavefronts. The fundamental mechanism for this propagation is known as Huygens' principle, according to which every point on a wave is a source of spherical waves in its own right.
