23 of Monochromatic electromagnetic of radiation from a distant source passes of through a slit. The diffraction pattern is observed on a screen 2.50 m from the at slit. If the width of the central maximum IS is 6.00 mm, what is the slit width if the wavelength is (a) 500 nm (visible light); (b) 50 um (infrared radiation); (c) 0.500 S nm (X-rays)? [Ans: 0.416 mm, 41.6 mm, 4.16x104 mm
