The  focus of a concave mirror is half of the radius of the mirror  therefore the radius would be 32 cm

What will be the radius of the Surface mirror?

It is given that the focus of the surface mirror is f=16 cm

since the focus of the concave mirror is half of the radius then from the

formula.

[tex]F=\dfrac{r}{2}[/tex]

[tex]16=\dfrac{r}{2}[/tex]

r= 32 cm

Hence the  focus of a concave mirror is half of the radius of the mirror  therefore the radius would be 32 cm.
