Rays diverge from a point source of a wavefront that is

Ray diverging from a point source from a wave front that is

Rays diverging from a point source from a ………… wavefront.

Rays diverging from a point source from a ………… wavefront.

For light diverging from a point source : a) the wavefront is spherical b) the intensity decreases in proportion to the distance squared c) the wavefront is parabolic d) the intensity at the wavefront does not depend on the distance

For point source, the wavefront is
