WebSep 25, 2024 · Radio waves, X-rays and gamma rays can pass through your body. But you can’t see them or feel them. Electromagnetic radiation travels in little packets ( quanta) of energy. These charge-less bundles of energy are called photons. They travel at the speed of light (2.998 × 108 m/s) in a vacuum.
WebRadio waves. Radio waves are used for communication such as television and radio. Radio waves are transmitted easily through air. They do not cause damage if absorbed by the human body, and they can be reflected and refracted to change their direction. These properties make them ideal for communications.
