Calculate fringe width in Young's experiment, if screen is placed at 1.5 m distance from the slits separated by 0.5 mm and wavelength of light used is 500 nm.

Explanation

To calculate the fringe width in Young's experiment, we can use the formula:

\[ \text{Fringe Width} (β) = \frac{\lambda D}{d} \]

where:
- \( \lambda \) = wavelength of light used
