Use Huygens' construction to explain the formulation of a wavefront.

1.	Use Huygens' construction to explain the formulation of a wavefront.
Answer» Considering a point source of monochromatic light S in a homogeneous medium. The light waves travel with the same speed(V) in all the DIRECTIONS. After the TIME ′t′, the waves will reach all the points which are at a distance vt from S. This is the spherical wavefront XY. LET A, B, C be points on the wavefront. To find the new wavefront after a time Δt, we draw spheres of radius vΔt with A, B and C as CENTRES. The tangents drawn to these spheres is the new spherical wavefront.Explanation:hope this helps
