The biological effects of a given dose of electromagnetic energy generally become more serious as the energy of the radiation increases: Infrared radiation has a pleasant warming effect; ultraviolet radiation causes tanning and burning; and X rays can cause considerable tissue damage. What energies in kilojoules per mole are associated with the following wavelengths:
infrared radiation with λ = 1.63 x 10 -6 m?
ultraviolet light with λ = 224 nm?
X rays with λ = 5.32 nm?
