We encounter a large number of waves every day without realizing it. One such source is radio waves. A typical frequency for radio transmission is 680 kHz. How much energy does one mole of radio waves carry? X rays used by doctors to view bones are much more energetic than radio waves. Determine the energy of one mole of X ray photons (3.8 x 1017 Hz).

  • chemistry - ,

    E for one atom = h*frequency.
    Multiply by 6.022E23 to determine E in a mole. Both parts are done the same way
