In Yong’s double slit experiment, monochromatic light of wavelength \( 5000 \, \mathring{A}\) is used. The slits are \( 1.0 \, \text{mm} \) apart and screen is placed at \( 1.0 \, \text{m} \) away from slits. The distance from the centre of the screen where intensity becomes half of the maximum intensity for the first time is __________ \( \times 10^{-6} \, \text{m} \).
