A beam of light of wavelength $600 \mathrm {~nm}$ passes through a slit that is $3.1 \times 10 ^ { - 5 } \mathrm {~m}$ wide, and then goes on to a screen that is $2.2 \mathrm {~m}$ from the slit. On the screen, how far is the second dark fringe from the center of the diffraction pattern?

A) $4.2 \mathrm {~cm}$
B) $2.1 \mathrm {~cm}$
C) $6.3 \mathrm {~cm}$
D) $8.5 \mathrm {~cm}$
E) $3.9 \mathrm {~cm}$
