Five spherical mirrors are made from the same sphere. The uncommon thing among the mirrors is……….

• A. radius of curvature
• B. focal length
• C. pole
• D. None of these

Answer 1

The correct option is C

pole

1. Five spherical mirrors are made from the same sphere. The uncommon thing among the mirrors is the pole.
2. Since, all five are made from the same sphere, their radius of curvature and focal length will remain the same.
3. As the length of all five can be different, the position of all will be different.

Thus, the correct option is (c).
