Radio Waves – The What and How

 

Electromagnetic waves are the way energy is transported around us. The energy is emitted and absorbed by particles and flows through the world in the form of a wave. But Electromagnetic waves are further divided, depending on the amount of energy they possess and the length of their waves i.e. radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.

One of the most important discoveries of modern science has been radio waves. Radio waves are the electromagnetic radiation waves that have frequencies between approximately 3 kHz to 300 GHz, which is lower than that of visible light. Radio waves are of special importance, because they surround us on a daily basis, as opposed to other electromagnetic rays such as X-rays. Our immediate living environment includes mobile phones, microwave ovens, Wi-Fi internet connections, radio and television transmissions etc.

Recently, there has been a lot of hue and cry over the health effects of radio-frequency waves on the human body. But the truth is that in all the years of use of such devices, there has been no evidence that there are any adverse health effects due to long-term exposure to radio frequency radiation. The truth is that the radio waves that surround us in our immediate environment have such low energy that the y do not impact our body in any way, so forget about impacting it negatively!

It is in fact the opposite end of the electromagnetic spectrum,with radiation that has frequency higher than visible light that is harmful for us. Ultraviolet radiation, X-rays and gamma rays are the ones that can cause disruption in our body’s DNA, which can lead to disease and death.

The distinction between Radio Waves and UV and Gamma Rays is vast. Radio waves help us further technology and communication, and are completely harmless. The distinction between Radio Waves and UV and Gamma Rays is the difference between life and death.
