1. The problem statement, all variables and given/known data Light from a laser with a wavelength of 760 nm is directed at a diffraction grating of 1500 lines/cm. If the diffraction grating is located 1.5 m from the screen, calculate the distance between adjacent bright fringes. 2. Relevant equations Δx = Lλ / d 760 nm = 7.60 x 10^-7 m = λ 1.5 = L 1cm/1500 = 6.67 x 10^-6 m = d 3. The attempt at a solution Δx = (1.5 m)(7.60 x 10^-7 m) / (6.67x 10^-6 m) = 1.71 x 10^-13 m I'm not sure if this is correct please help.
