In a diffraction grating experiment, green light of wavelength λ = 533 nm is directed on a diffraction grating that has N = 577 /mm lines. The diffraction pattern is projected on a screen that's located 172.5 (cm from the grating. Find the distance between the first bright fringe and third dark fringe on the screen.
your answer should be in SI units (meters)
This is a diffraction grating problem, you can not use the approximation
