Question

The focal lenth of one mirror is 15 cm, and then their centre of curvature is at ___distance from the pole.​

Answer 1

Answer:

30 cm

Step-by-step explanation:

distane between pole and focus is radius of curvature (r)

We know r =2f so r=(2×15)cm =30cm

Answer 2

Answer:

30 cm

Step-by-step explanation:

f=c/2

here f = focal length and c = centre of curvature.

therefore center of curvature=30 cm
