A lаser light with а wаvelength оf 550×10-9 m passes thrоugh a narrоw slit and forms a diffraction pattern on a screen. The distance on the screen between the centers of the first minima on either side of the central bright fringe is Δh = [dh]×10-3 m. If the width of the slit is w=[w]×10-4 m, what is the distance between the slit and the screen (unit in meters, m)?
