A plane wave is incident on a concave mirror of radius R. The shape of the reflected wavefront will be
- A diverging spherical
- B plane wavefront
- C converging spherical
- D cylindrical
Answer & Solution
Correct Answer
(C) converging spherical
Step-by-step Solution
Detailed explanation
The reflected wavefront will be converging spherical. The shape of the reflected wavefront depends on the curvature of the concave mirror. Since the concave mirror converges parallel incident rays to a focal point, the reflected wavefronts will take the shape of spherical…
