In Young's double slit experiment, monochromatic light of wavelength $\displaystyle 5000 \AA$ is used. The slits are $\displaystyle 1.0$ mm apart and screen is placed at $\displaystyle 1.0$ m away from slits. The distance from the centre of the screen where intensity becomes half of the maximum intensity for the first time is $\displaystyle \_\_\_\_$ $\displaystyle \times 10^{-6}$ m.
