In Young's double slit experiment, the slits separated by $0.6 \mathrm{~mm}$ are illuminated with light of $6600 Å$. Interference pattern is obtained on a screen placed at $4 \mathrm{~m}$ from slits. The minimum distance from the central maximum at which the average intensity is $50 \%$ of the maximum value is
