Problem

In a double-slit experiment, green light (

5303\text{Å}

) falls on a double slit having a separation of

19.44\ \mu\text{m}

and a width of

4.05\ \mu\text{m}

. The number of bright fringes between the first and the second diffraction minima is: [11 Jan 2019 II] (a) 10 (b) 05 (c) 04 (d) 09
