Question

if radius of cuvature of spherical mirror is 12 cm then what is its focal​

Answer 1

focal length f of concave mirror = 1/2 of radius of curvature = 12/2 = 6 cm .

Answer 2

Answer:

F =R/2

Step-by-step explanation:

Radius of curvature, R= 12 cm Radius of curvature of a spherical mirror = 2 cm Focal length (f) R= 2f f= R/2 = 12/ 2 = 6
