Write down the formula for the distance between two consecutive bright fringes or two consecutive dark fringes in Young's Double Slit Experiment.

(N/A) In Young's Double Slit Experiment,the distance between two consecutive bright fringes or two consecutive dark fringes is known as the fringe width,denoted by $\beta$.
The formula for fringe width is given by:
$\beta = \frac{\lambda D}{d}$
Where:
- $\lambda$ is the wavelength of the monochromatic light used.
- $D$ is the distance between the slits and the screen.
- $d$ is the distance between the two slits.
