Answer:

6cm

Explanation:

Radius of Curvature = 2 Focal Length

So ,

R = 12 cm

So,

12=2F => F = 6 cm

Hope this helps you !

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
