a) A beam of monochromatic light is incident on a single slit of width 0.600 mm. A diffraction pattern forms on a wall 1.40 m beyond the slit. The distance between the positions of zero intensity on both sides of the central maximum is 1.90 mm. Calculate the wavelength (in nm) of the light. Round your answer to the nearest nm. b) The hydrogen spectrum includes a red line at 656 nm and a blue-violet line at 434 nm. If...
