A light having wavelength (lambda) from various sources passes via a slit. The diffraction pattern is viewed on a screen 2.5m from the slit. When the width of the central maximum is 6.0 mm then find out the slit width if the wavelength is:
i) 500 nm (visible)
ii) 50.0 micrometers (infrared)
iii) .500 nm (x-ray)
