In two separate setups for Biprism experiment using same wavelength, fringes of equal width are obtained. If ratio of slit separation is $2 : 3$ then the ratio of the distance between the slit and screen in the two setups is

Options:

Answer:

Solution:

Fringe width, $W = \frac{λ \cdot D}{d}$ For constant $W$ and $λ$ , $D \propto d$ $∴ \frac{D _{1}}{D _{2}} = \frac{d _{1}}{d _{2}} = \frac{2}{3}$
