Which of the following electromagnetic waves is given off as heat?
A
Radio Waves
B
Infrared Rays
C
Visible Light
D
Gamma Rays
Explanation: 

Detailed explanation-1: -Infrared radiation is what we like to describe as heat. We can’t see infrared waves, but we can feel them. Your body gives off heat, so it is an emitter of infrared radiation.

Detailed explanation-2: -Infrared radiation (IR), sometimes referred to simply as infrared, is a region of the electromagnetic radiation spectrum where wavelengths range from about 700 nanometers (nm) to 1 millimeter (mm). Infrared waves are longer than those of visible light, but shorter than those of radio waves.

Detailed explanation-3: -(a) Infra-red waves are also known as heat waves because they raise the temperature of the object on which they fall. They also affect the photographic plate and are readily absorbed by most materials.

Detailed explanation-4: -Infrared rays are electromagnetic waves with wavelengths shorter than those of radio waves. Infrared rays have a higher frequency than radio waves, so they have more energy than radio waves. Because you can feel the energy of infrared rays as heat, these rays are often called heat rays.

Detailed explanation-5: -Long-wave infrared radiation (often abbreviated to LWIR) and short-wave infrared radiation (often abbreviated to SWIR). Common television remotes emit signals in the form of short-wave infrared radiation. More items
