    Spherical wave fronts, 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

    Correct Answer: C

    Solution :

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