In Young’s double slit experiment, the screen is kept at a distance of $1\cdot2\text{ m}$ from the plane of the slits. The two slits are separated by $5\text{ mm}$ and illuminated with monochromatic light having wavelength $600\text{ nm}$. Calculate:
(i)[1.5]
Fringe width i.e. fringe separation of the interference pattern.
(ii)[1.5]
Distance of 10th bright fringe from the centre of the pattern.
