Question

with what type of source of light are spherical wave front assiciated​

Answer 1

Answer:

When the source of light is a point source the wavefront formed will be spherical wavefront. Point source means the source of light is so small that it is considered as point. It can be considered as dimensionless. For example: - Ripples in water are in the form of concentric circles which are spherical wavefronts.

Answer 2

Such wavefront is called a spherical wavefront. When the source of light is linear, all the points equidistant from the linear source lie on the surface of a cylinder.
