Given that

Wavelength of the light \lambda = 600 nm = 600 * 10^{-9} m

Angular width of the fringe \theta = 0.1\degree

Spacing between the two slits = ?

Step 1: Step up a formula for distance between the two slits.

We know that

The angular fringe width depends on the light wavelength used, and the distance between two slits

\theta = \frac{\lambda}{d}

Distance between two slits   d = \frac{\lambda}{\theta}

Step 2: Identifying the spacing between the two slits

d = \frac{600 * 10^{-9}}{0.1* \frac{\pi}{180}}                \because1\degree=\frac{\pi}{180}rad

d = \frac{600 * 180 * 10^{-9}}{0.1 \pi }

d = 3.44 *10^{-4} m

d = 0.344 mm

Therefore, spacing between the two slits d = 0.344 mm
