What Is a wavefront? How can we interpret it?
why does a point source produce spherical wavefront because waves are emitted in all the directions in 3 dimensionCultural issue: I would call that shape and reserve 'structure' for 'how it's built and with what'.
Other issue with 'identify': they don't have social security numbers.
Double trouble with 'how to identify them and their structures' .
Google is your friend: a wave is a propagating disturbance and from that I would loosely consider the wavefront as the locus of 'first arrivals'.
For identification some form of detection seems indicated and for shape you would need extended detection.
Shape is relative: for a lot of phenomena the plane wave concept is already adequate, for others you need a bit more (cylindrical, spherical).
got it , but can you please tell what will be the wavefront for converging and diverging rays and why?A disturbance proagates with a certain speed. If the medium is isotropic that speed will be the same in every direction, so after a given time the wavefront () has propagated over equal distances in all directions. The locus of points that have the same distance to a given origin is a spherical shell
