as the frequency of an electromagnetic wave increases, the amount of energy in that wave... increases. stays the same. decreases.

Answer

# Brief Explanations: The energy of an electromagnetic wave is directly proportional to its frequency, as described by the equation $E = hf$ (where $E$ is energy, $h$ is Planck's constant, and $f$ is frequency). So as frequency increases, energy increases. # Answer: increases.
