Broad spectrum white light containing wavelengths from 420 nm to 730 nm falls on arefraction grating with 7900 slits / cm. How wide is the first order spectrum on a screen3.1 m away? (Hint: solve for theta for first order fringe for each wavelength, then usetrig to solve for distance from straight through direction location on screen to positionof each wavelength on screen. Subtract these distances to get width of first orderspectrum).
