There are three types of wavefronts. They are:
(i) Spherical wavefront:
→ The Wavefront from the point source is in the form of a concentric sphere is called a spherical wavefront.
(ii) Cylinder wavefront:
→ The wavefront from the linear light source is in the form of the co-axial axis called a cylinder wavefront.
(iii) Plane wavefront:
→ The wavefront from the distant source is in the form of a plane is called a plane wavefront.
