Waves and Electromagnetic Spectrum Review

Aria, Samuel, and Ethan are studying for their physics exam. They are discussing how the energy of electromagnetic waves changes as you move from radio waves, which are used in their car radios, to gamma rays, which are used in cancer treatment. How does this energy change?
