Write the formula for fringe width.
(N/A) The fringe width $(\beta)$ in Young's Double Slit Experiment is the distance between two consecutive bright or dark fringes.
It is given by the formula:
$\beta = \frac{\lambda D}{d}$
Where:
$\lambda$ = Wavelength of the monochromatic light used.
$D$ = Distance between the slits and the screen.
$d$ = Distance between the two coherent sources (slits).
It is given by the formula:
$\beta = \frac{\lambda D}{d}$
Where:
$\lambda$ = Wavelength of the monochromatic light used.
$D$ = Distance between the slits and the screen.
$d$ = Distance between the two coherent sources (slits).
