Q: What is the distance between the pole and focus of a spherical mirror?
  • A. 2R
  • B. R/4
  • C. R/2
  • D. R
Correct Answer: Option C - The distance between the pole and focus of spherical mirror is R/2. The distance from the pole to the focal point is called the focal length (f). R = 2f f = R/2
