Radiofrequency radiation is primarily used for?

• A. Thermal heating of food
• B. Communication
• C. Medical imaging
• D. Nuclear power generation

Answer: (B)

Radiofrequency radiation consists of non-ionizing electromagnetic waves in the range used to carry wireless signals. The biggest, most widespread use of these waves is for communication: transmitting and receiving information for radio, television, cellular networks, Wi‑Fi, Bluetooth, and satellite links. The waves are easily guided by antennas, can be modulated to encode voice, data, or video, and propagate through air, making them ideal for long-distance and local wireless communication. While other RF applications exist—such as heating food in microwave ovens or RF techniques in medical imaging—these are specialized cases and do not define the primary role of RF energy in everyday technology. Nuclear power generation uses nuclear reactions and does not rely on radiofrequency communication.
