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

They will remain spherical with the same curvature, both in magnitude and sign

They will become plane wave fronts

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

They will remain spherical, but with different curvature, both in magnitude and sign

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