Practice Problem 1-1 Answer Which is higher in energy? (a) Infrared radiation of 1715 cm 1 or of 2800 cm 1 ? (b) Radio-frequency radiation of 300 MHz or 60 MHz? (c) Infrared radiation with = 1.0 x 10 6 m or an X ray with = 3.0 x 10 9 m? Remember that energy is directly proportional to frequency ( ), and inversely proportional to wavelength ( ). A larger frequency therefore corresponds to HIGHER energy, while a larger wavelength corresponds to a SMALLER energy. (d) Radiation with = 4.0 x 10 9 Hz or radiation with = 9.0 x 10 6 m? Use the expression c =  to convert the given to its corresponding frequency: Practice Problem 1-2 Answer Because IR absorptions can be expressed either in micrometers or in wavenumbers, it is useful to be able to
