In Young's double slit experiment the two slits are $\displaystyle 0.6$ mm distance apart. Interference pattern is observed on a screen at a distance $\displaystyle 80$ cm from the slits. The first dark fringe is observed on the screen directly opposite to one of the slits. The wavelength of light will be
\_\_\_\_ nm.
