- What is correct about an electromagnetic wave in vacuum (or free space)? Group of answer choices The amplitude of the electric and magnetic fields are the same. The net energy in the electric and magnetic fields are the same. The energy densities in the electric and magnetic fields are the same. When in the vacuum, electromagnetic waves of higher frequencies travel faster than their lower frequency counterpart.A plane electromagnetic wave is traveling in a vacuum.
