Answer:

(a) Light diverging from a point source.(b) Light emerging out of a convex lens when a point source is placed at its focus.(c) The portion of the wavefront of light from a distant star intercepted by the Earth.

Explanation:(a) (a) Spherical. The shape of the wavefront in light diverging from a point source is spherical.

(a) Spherical. The shape of the wavefront in light diverging from a point source is spherical.(b) Plane. The shape of the wavefront in case of a light emerging out of a convex lens when a point source is placed at its focus is a parallel grid.

(a) Spherical. The shape of the wavefront in light diverging from a point source is spherical.(b) Plane. The shape of the wavefront in case of a light emerging out of a convex lens when a point source is placed at its focus is a parallel grid.(c) Plane (a small area on the surface of a large sphere is nearly planar). The portion of the wavefront of light from a distant star intercepted by the Earth is a plane.
