Four examples of electromagnetic (EM) waves are radio waves, microwaves, infrared radiation, and visible light. These waves differ in wavelength and frequency, but they all travel at the speed of light in a vacuum. Radio waves are used for communication, microwaves for cooking and some communication, infrared radiation for thermal imaging, and visible light is what we see with our eyes.
