5-6 A grating has a line density of 1010 cm , and a screen perpendicular to the ray that makes the central peak of the diffraction pattern is 3.0 m from the grating. If light of two wavelengths, 630 nm and 680 nm, passes through the grating, what is the separation on the (flat) screen between the fifth-order maxima for the two wavelengths? 0.07575 m Submit Answer You have entered that answer before Incorrect.
