- The electromagnetic spectrum represents the different forms of electromagnetic radiation.
- Light is classified as electromagnetic radiation because electrical and magnetic fields vibrate in a light wave.
- Radiant energy is energy that travels by radiation. An example of this is light.
- Heat radiation, also known as infrared waves, cannot be seen by your eyes but can be felt by your skin.
- Microwaves are one type of electromagnetic radiation.
- Radio waves can be used to communicate with satellites.
- Because gamma rays have the highest energy of all electromagnetic radiation, they are the most damaging to human tissue.
- Compared to all other types of electromagnetic radiation, radio waves have the lowest frequency.
- An overexposure to ultraviolet rays can result in sunburns and skin cancer.
- An empty plate does not heat up in the microwave because it lacks water molecules for the microwaves to excite.
