Problem 4 A laser with wavelength 656 nm is incident on a diffraction grating with 1600 lines mm a 15 points Find the smallest distance from the grating that a converging lens with focal length of 20 cm be placed so that the diffracted laser light converges to a point 1 0 meter from the grating b 15 points If a screen is placed at the location from part a how far apart will the two first orde beams appear on the screen If you did not solve part a use a distance of 0 5 m
