Question

what is one use for infrared waves?
television signals
cooking
thermal imaging cameras

Explanation:

Infrared waves are electromagnetic waves with longer wavelengths than visible light. Thermal imaging cameras detect infrared radiation emitted by objects. The heat (infrared radiation) from different objects (with different temperatures) is captured by the camera, allowing visualization of temperature differences. Television signals mainly use radio waves. While some cooking appliances (like infrared grills) use infrared, thermal imaging cameras are a more direct and well - known use of infrared waves in a scientific/technical context.
