The normal lens on a $35 \mathrm{~mm}$ camera has a focal length of $50.0 \mathrm{~mm}$ . Its aperture diameter varies from a maximum of $25 \mathrm{~mm}(f / 2)$ to a minimum of $3.0 \mathrm{~mm}(f / 16)$ . Determine the resolution limit set by diffraction for $(f / 2)$ and $(f / 16)$ . Specify as the number of lines per millimeter resolved on the detector or film. Take $\lambda=560 \mathrm{~nm}$ .
