A light source emits two different wavelengths, one of perpendicular to a lattice, it is found that the 3rd order of 600 nm overlaps with the 4th order image formed other wavelengths emitted by the light source!
ths, one of which is 600 nm. When incident light is 3rd order image formed by light with a wavelength ge formed by the other wavelength. Determine the ce!
