• 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
