A diverging mirror creates a virtual image 5 cm from the silvered side.?
ByWhen the object is 10 cm from the glass side of the mirror. What is the radius of curvature of the mirror (in cm)?

From the mirror eqn we have 2/R = 1/s + 1/s’
2/R = 1/10 + 1/(-5) = -0.10
So R = 2/(-0.1) = -20 cm
So the radius of curvature = 20 cm
