As the frequency of light increases, the energy of a photon of that light increases. The relationship is a simple proportionality:
The exact relationship is given by Planck's Law on page 80, but you will
be able to solve problems using the proportional relationship.
To turn the proportionality into an equation, write
Example. What is the ratio of the energy of a 1021 Hz gamma-ray to a 100 MHz radio wave?
