Question

the force length of cancave mirror is 7.5 cm.what is the radius of curvature​

Answer 1

Explanation:

$\huge\fbox\red{A}\fbox\pink{n}\fbox\purple{S}\fbox\green{w}\fbox\blue{E}\fbox\orange{r}$

Radius of Curvature(R)=2 F

                                     = 2(7.5)

                                     = 15 cm

∴Radius of curvature of a mirror with focal length of 7.5 cm is 15 cm.
