Asked by keko
Light consisting of two wavelengths which differ by 160nm passes through a diffraction grating with 2.5 x105
lines per meter. In the diffracted light the third order of one wavelength coincides with fourth order of the
other. What are the two wavelengths and at what angle of diffraction does this coincidence occur.
