In a Young's double slit experiment, the slits are separated by $\displaystyle 0.3$ mm and the screen is $\displaystyle 1.5$ m away from the plane of slits. Distance between fourth bright fringes on both sides of central bright fringe is $\displaystyle 2.4$ cm. The frequency of light used is \_\_\_\_ $\displaystyle \times 10^{14} \mathrm{~Hz}$.
