Select: FM radios, microwaves, TV remote controls, X‑rays.
- FM radios use radio waves (electromagnetic).
- Microwave ovens/communications use microwaves (electromagnetic).
- TV remote controls send infrared signals (electromagnetic).
- X‑rays are a form of electromagnetic radiation used in imaging.
Alarm clocks typically produce sound (mechanical pressure waves), so they do not normally use electromagnetic waves (unless it’s a radio/alarm with a built‑in radio or light feature).
