Spherical wavefronts, emanating from a point source, strike a plane reflecting surface. What will happen to these wave fronts, immediately after reflection?

View answer and explanation

Correct option: C

They will remain spherical, with the same curvature, but sign of curvature reversed.

Option C is correct because reflection from a plane surface reverses the direction of the wavefronts, but their curvature remains the same in magnitude, only the sign changes.
