Sodium vapor lamps are used to illuminate streets and highways. the very bright light emitted by these lamps is actually due to two closely spaced emission lines in the visible region of the electromagnetic spectrum. one of these lines has a wavelength of 5.890 x 10⁻⁷ m, and the other line has a wavelength of 5.896 x 10⁻⁷ m. a) what are the wavelengths of these radiations in centimeters? b) calculate the frequencies of these radiations. show work
