Find the angular fringe width in Young's double slit experiment using a monochromatic light of wavelength 500 nm when the slits are separated by 2.5 mm.

Explanation

To find the angular fringe width in Young's double slit experiment, we can follow these steps:

### Step 1: Understand the formula for angular fringe width
The angular fringe width (β) in Young's double slit experiment is given by the formula:
\[ \beta = \frac{\lambda}{d} \]
where:
