Problem

Select the correct mathematical form of the thin lens formula when measurements follow the Cartesian sign convention. (a) 1f=u+vuv\displaystyle \frac{1}{f}=\frac{u+v}{uv} (b) 1f=1v−1u\displaystyle \frac{1}{f}=\frac{1}{v}-\frac{1}{u} (c) 1f=1v+1u\displaystyle \frac{1}{f}=\frac{1}{v}+\frac{1}{u} (d) 1f=v−uuv\displaystyle \frac{1}{f}=\frac{v-u}{uv}
