If Light of Wavelength $600 \mathrm{~nm}$ Is Used to Locate an Electron to Within One Wavelength

If light of wavelength $600 \mathrm{~nm}$ is used to locate an electron to within one wavelength of the light, what is the minimum uncertainty in the electron's momentum?

A) $1.8 \times 10^{-32} \mathrm{~kg} \cdot \mathrm{m} / \mathrm{s}$
B) $1.8 \times 10^{-28} \mathrm{~kg} \cdot \mathrm{m} / \mathrm{s}$
C) $8.8 \times 10^{-29} \mathrm{~kg} \cdot \mathrm{m} / \mathrm{s}$
D) $1.1 \times 10^{-27} \mathrm{~kg} \cdot \mathrm{m} / \mathrm{s}$
E) $1.2 \times 10^{-32} \mathrm{~kg} \cdot \mathrm{m} / \mathrm{s}$
