## Homework Statement

Where on the axis of a concave mirror would you place an object to get a half-size image? Express the object distance in terms of the focal length f. Follow the sign convention.

## Homework Equations

(1/q)+(1/p)=(1/f)

f=(2/R)

## The Attempt at a Solution

I attempted to use the object distance plus image distance to solve for f (I just got f=q+p), but the online homework system says that is wrong. Are these the correct formulas and what should I be doing?
