The 630-nm light from a helium-neon laser irradiates a grating. The light then falls on a screen where the first bright spot is separated from the central maximum by 0.55 m . Light of another wavelength of light produces its first bright spot 0.37 m from its central maximum. Required:
Determine the second wavelength.
