Question 31

Circular wavefronts emitted by a point source S S\,S travel through a medium and strike a flat, reflecting barrier. The barrier is vertical, with the source S S\,S on its left. The wavefronts are reflected so that they appear to diverge from a virtual source S1 S_1\,S1​ located on the right side of the barrier, at the same distance from the barrier as SSS.

Which statement correctly describes the reflected wavefronts?

A

The reflected wavefronts lie to the left of the barrier, travel to the left, and are curved such that their center of curvature is at the virtual source S1S_1S1​.

B

The reflected wavefronts lie to the left of the barrier, travel to the left, and are curved such that their center of curvature is at the real source SSS.

C

The reflected wavefronts lie to the right of the barrier, travel to the right, and are curved such that their center of curvature is at the virtual source S1S_1S1​.

D

The reflected wavefronts lie to the left of the barrier, travel to the right, and are curved such that their center of curvature is at the real source SSS.
