light with a wavelength of 520 nm abd 630 nm passes through a diffraction grating that contains 6000 lines/cm.
a) sketch a diagram of the image produced from m=0 to m=2, label the order of each fringe
b) calculate the angles for the first and second order maxima that would appear on the screen
i have no idea where to start someone please help!
