Answer:
6cm
Explanation:
Radius of Curvature = 2 Focal Length
So ,
R = 12 cm
So,
12=2F => F = 6 cm

Given :-
Radius of Curvature of a concave mirror is 12 cm
To Find :-
Focal length of that concave mirror.
Solution :-
❍ To calculate the focal length of the concave mirror we have to substitute the values in the formula ::
2F = R
Where,
- F denotes focal length
- R denotes radius of curvature
Finding the focal length :-
⤳ 2F = 12 cm
⤳ F = 12/2 cm
⤳ F = 6 cm
⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━⠀⠀⠀⠀
- Henceforth, the focal length of the concave mirror is 6 cm
