Coherent Light Rays Of Wavelength

Coherent light rays of wavelength A strike a pair of slits separated by distance d at an angle θ1 as shown in Figure P37.14. Assume an interference maximum is formed at an angle θ2 a great distance from the slits. Show that d (sin θ2 – sin θ1) = mA, where m is an integer.
