14. A wavelength of 254 nm was formerly used in certain analyses for organic compounds because it is the most intense 8 wavelength emitted by a mercury lamp. Today, however, mercury lamps are no longer used in those instruments. a. What is this wavelength in centimeters? b. What is the frequency corresponding to this wavelength? c. What is the energy of light of this wavelength? d. What is the wavenumber corresponding to this wavelength? 15. Which has a greater frequency, light of wavelength 627 A or light of wavelength 462 nm?
