Light from a laser beam with a wavelength of 600 nm passes through a narrow single slit and observed on a screen 1.5 m behind the slit. The first minimum of the diffraction pattern is 1.5 cm from the central maximum. How wide is the slit? Please be specific and show your work, much appreciated. a) 2.2 m b) 10 m c) 4.4 m d) 1.1 m e) 0.56 m
