Question: A diffraction grating with 875 slits with 2.38×106 m spacing is illuminated with monochromatic light (light of a single wavelength). The central maximum of the pattern has angular width of 6.24×104 rad.
Question I: What is the wavelength of the light?
Show how you get the answer, so that I can better understand how to do it. Thanks.
