ELECTROMAGNETIC RADIATION

Q-Give four properties of infrared radiation.

A-1-Infrared radiation, like all radiation, travels at a speed of 299,792,458 meters per second.

2-Infrared light can exhibit both wave and particle nature at the same time.

3-Depending on the nature of the material that infrared radiation strikes, it can either be absorbed or reflected.

4-Infrared radiation increases the thermal energy in particles.

Q-Give few medicinal effects of infrared radiation.

A-1-Used to reduce the inflammation of the throat, ear and nose

2-Used as an aid in stress management

3-Reduces pain arthritis

4-it eases kidney function

Q-How does infrared radiation work?

A-The emission of infrared radiation from an object is possible when heated. The atoms and the molecules in the object start to vibrate, thereby radiating infrared in the form of heat. When the objects are not hot enough to produce visible light, they radiate infrared. Also, heat production is independent of the temperature of the surroundings.
