1. Coherent light passes through two narrow slits which are 0.4 mm apart. As a result, the third maximum is created at an angle of 1.5° from the central axis. DI A) Calculate the wavelength of this light, in meters. B) If the screen is 5 meters from the slits, how far is this 3rd maximum from the central maximum? C) Calculate the angle to the 6th minimum of the interference pattern. D) How many total maxima are projected within a 20° angle to the central axis? (Both sides) 2. A diffraction grating produces a 2nd maximum at a 40° from the central axis. A) If the light has a 550 nm wavelength, what is the line density of this grating, in lines per centimeter? B) At what angle would 700 nm light produce a 2nd maximum when passing through this grating?
