Problem

In a Young slits experiment, the two slits are separated by a distance of

d

and a nearby screen, on which an interference pattern is formed, is a distance

D

away. If the wavelength of light is

\lambda

, the number of maxima per metre in the interference pattern is given by a.

\frac{d}{\lambda D}

. b.

\frac{\lambda d}{D}

. c.

\frac{\lambda D}{d}

. d.

\frac{dD}{\lambda}
