Question

:) A point source of light is situated at large
distance, the nature of wave front at the point under
consideration is;​

Answer 1

Answer:

For a point source of light, the wave front produced is spherical wave front. If a point is cosidered at a large distance(usually considered close to infinity) from a point light source, then at that point a plane wavefront will be found since curvature decreases with the increase of distance.
