Reflection of spherical wave from plane

[ThetaPi]

Problem statement.

A spherical wave (from a point source) reflects from a planar surface. Draw a ray diagram and sketch some wavefronts for the reflected wave.

Attempt

It is easy to sketch some wavefronts for the reflected waves; however, how is it possible to draw a ray diagram for this? I have only done ray diagrams for reflections from mirrors into a person's eyes.

The same as for the eye case only that this time the rays converge at their source and diverge ( do not take these words literally) away. Use a point source on a peace of paper draw rays around it than place a line which represents the planar surface. The rest is quite intuitive.

Look up the Law of Reflection, that is the key here.
