Infrared Rays are electromagnetic waves with wavelengths shorter than those of radio waves.
Higher energy rays have more energy than lower energy waves.
You feel the energy of infrared rays as heat.
Heating lamps have bulbs that give off mostly infrared rays and very little visible light.
Infrared heaters are used to keep food warm or heat up rooms quickly.
Most objects give off some infrared radiation.
Hotter objects give off infrared rays with more energy and higher temperature.
Infrared cameras take pictures using infrared radiation instead of visible light.
These pictures are called thermal images, which is an image that shows regions of different temperatures in different colors.
Used by search and rescue teams to locate people during emergencies.
