Steps to Draw Huygens’ Wavefront…

Steps to Draw Huygens’ Wavefront –
(i) At time a Huygens’ wavefront, Spherical wavefront known each point on the wavefront from spheres of radius vt. (Here, which wavefront has to be at the time t and the speed of wave v.)
(ii) All these spheres a common tangent
(iii) All these points combining, At time t our new tangent we get.
