Problem

X rays have wavelengths on the order of 1 x 10-10 m. Calculate the energy of 1.0 x 10 -10 m X rays in units of kilojoules per mole of X rays. (1 mol X rays = 6.022 x 10  23 X rays).

AM radio waves have wavelengths on the order of 1 x 10 4 m. Calculate the energy of 1.0 x 10 4 m radio waves in units of kilojoules per mole of radio waves.

Consider that the bond energy of a carbon–carbon single bond found in organic compounds is 347 kJ/mol. Would X rays and/or radio waves be able to disrupt organic compounds by breaking carbon–carbon single bonds?

Solution

The relationship between energy and wavelength is inversely proportional. A calculation for energy as it relates to wavelength includes the speed of light and Planck’s constant. The equation describing this relationship is shown below:
