Light of wavelength 590 nm(590 x 10^-9 m) is used to produce a double slit diffraction pattern where the second order image is 0.042 m from the central image using a diffraction grating constant of 4.8 x 10^-5 m. How far is the screen from the slits? SHOW ALL YOUR WORK. USE OF THE SMALL ANGLE APPROXIMATION FORMULA IS FINE.
