  • How is electromagnetic energy transferred from one place to another?

  • The electromagnetic waves are the ocean waves, and the electromagnetic energy is produced from the waves carrying water from the middle of the ocean to the shore. That energy is best exemplified by the power needed to move all of that water across long distances. Actual electromagnetic energy transfer and generation are a little more complex.

  • How is energy transferred through sound and electromagnetic waves?

  • In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels.

  • What does it mean when an electromagnetic wave is emitted?

  • When an electromagnetic wave is emitted, it means energy transfers from source to target. You could think of EM wave as itself being made of energy. EM waves are made of photons (energy packets) which move in a periodic manner and travel to the target.

  • How do electric and magnetic fields transfer energy and momentum?

  • Thus, the electric and magnetic fields transfer energy and momentum in form of changing electric and magnetic fields. A very simple way of checking this fact is to allow EM waves to pass through a surface containing static charges. The charges will be set to motion by the electromagnetic field.
