Q: The distance between the pole and centre of curvature of a concave mirror of radius of curvature 100 cm is:
  • A. 50 cm
  • B. 200 cm
  • C. 25 cm
  • D. 100 cm
Correct Answer: Option D - Distance between pole and centre of curvature is radius of curvature. So radius of curvature is 100 cm.
D. Distance between pole and centre of curvature is radius of curvature. So radius of curvature is 100 cm.

Explanations:

Distance between pole and centre of curvature is radius of curvature. So radius of curvature is 100 cm.
