Question

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

• A. They will remain spherical with the same curvature, both in magnitude and sign.
• B. They will become plane wave fronts.
• C. They will remain spherical, with the same curvature, but sign of curvature reversed.
• D. They will remain spherical, but with different curvature, both in magnitude and sign.

Answer 1

Answer: (C)

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

Answer 2

: They will remain spherical, with the same curvature but sing of curvature reversed
