If focal length of a spherical mirror is 20 cm, then its radius of curvature is equal to
10 cm
20cm
5cm
40cm
Radius of curvature is twice of the focal length,
R = 2f
Hence, it is 40 cm.
If AB = 10 cm & DB = 40 cm (diameter)
What is radius of curvature & focal length?
If AB = 10 cm & DB = 40 cm (diameter). What is the radius of curvature & focal length?
If AB = 10 cm and DB = 40 cm (diameter). What is the radius of curvature and focal length?
