Solution: Monochromatic light of wavelength λ = 500 nm passes through a narrow slit of width a and on a screen 2.0 m from the screen the width of the central maximum is 3.0 mm. If the width of the slit in increased, the width of the central maximum is A) 3.0 mm B) larger than 3.0 mm C) smaller than 3.0 mm
