Long-wavelength electromagnetic radiation used for broadcasting and communication.
Electromagnetic radiation used in radar, communication, and ovens that transfer energy to food.
Electromagnetic radiation with wavelengths longer than visible red light; warm objects emit it.
Electromagnetic radiation that human eyes can detect.
Electromagnetic radiation with wavelengths shorter than visible violet light; excessive exposure can damage skin and eyes.

Order the Spectrum
Start with the longest wavelength (Radio Waves) and finish with the shortest, most energetic waves (Gamma Rays).
Reading
The spectrum moves from long waves with low energy to short waves with high energy. Radio Waves travel far and carry music and voice. Microwaves help phones talk to towers and heat food. Infrared Waves carry heat, and Visible Light is the tiny band we see. Ultraviolet (UV) comes from the sun and can cause sunburn. X-rays pass through soft tissue to show bones, and Gamma Rays carry the most energy of all.
Tip: Think "longer = safer, shorter = stronger."
