  • All electromagnetic waves carry energy.
  • Short waves with a higher frequency, carry more energy than long waves with a lower frequency.
  • Waves with more energy can be more damaging to the body. That’s why you must wear protection while getting an X-ray, but not when making popcorn in your microwave oven.
  • As you slide the arrow, watch how the energy goes up as the wavelength goes down.
