In contrast, visible light and longer-wavelength electromagnetic radiation, such as infrared, microwaves, and radio waves, consists of photons with too little energy to cause damaging molecular excitation, and thus this radiation is far less hazardous per unit of energy.
Re: AM radio waves bounce off the ionospher, what do FM radio waves bounce off. Radio waves are the same thing as light waves. But the wavelength of radio waves is much longer. An AM radio wave has a wavelength in the range from 13 to 60 metres (shortwave) or around 200 to 500 metres (broadcast band).
