Consider a monochromatic coherent light (^=600 nm) passes through a double-slit that has a separation f0.12 mm and 0.02 mm slit width. The irradiance pattern is observed on a viewing screen at a distance - (1.5 [m]) from the slit plane. a) Derive and describe an expression for the irradiance pattern on the screen using equations. b) How does the irradiance pattern change when the slit width is smaller than the wavelength of the light? b) How many bright fringes are there in the central diffraction maximum?
