What are the benefits of radio waves?
Radio waves are used for communication such as television and radio.
Radio waves are transmitted easily through air.
They do not cause damage if absorbed by the human body, and they can be reflected and refracted to change their direction.
These properties make them ideal for communications..
How do you explain radio waves to a child?
Radio waves make up part of the electromagnetic spectrum. These waves are packets of energy with differing wavelengths, similar to visible light waves, X-rays or gamma rays, except longer. A radio wave, like other electromagnetic waves, is similar to an ocean wave or any other type of wave.
Are radio waves dangerous?
It has been known for many years that exposure to very high levels of RF radiation can be harmful due to the ability of RF energy to heat biological tissue rapidly. … Exposure to very high RF intensities can result in heating of biological tissue and an increase in body temperature.
Who found radio waves?
Heinrich HertzIt was there that physicist Heinrich Hertz proved the existence of radio waves in the 1880s at a university now known as Karlsruhe Institute of Technology.
What are 3 facts about radio waves?
