Spherical wavefronts, 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.

Choose the correct option: (i) A surface on which the wave disturbance in same phase at all points is called a wavefront. (ii) The direction of a wave at a point is perpendicular to the wavefront through that point. (iii) The wavefronts of a wave originating from a point source is spherical. The wavefronts for a wave going along a fixed direction are planes perpendicular to that direction.
