Question: There are 5620 lines per centimeter in a grating that is used with light whose wavelength is 471 nm. A flat observation screen is located

There are 5620 lines per centimeter in a grating that is used with light whose wavelength is 471 nm. A flat observation screen is located at a distance of 0.750 m from the grating. What is the minimum width that the screen must have so the centers of all the principal maxima formed on either side of the central maximum fall on the screen?
