Wavefront: Wavefront is the location where all the points of a particular medium vibrate
Point source of Light has: Spherical Wavefront
Source at infinite distance has: Rectangular wavefront
Linear source has:
Direction of Propagation of Light is always perpendicular to that of Wavefront
Linear source has cylindrical wavefront
Wavefront : It is the locus of all the particles vibrating in the same phase.
32:51 because of coherent sources,at a point in the medium it is either dark or bright ie omega is same and phase diff doesnt depend upon time
