There has been some concern over the potential for microwaves to damage the brain, but the evidence suggests that it is unlikely. Microwaves are a form of electromagnetic radiation, similar to radio waves, but at higher frequencies. They are used in microwave ovens to heat food and in telecommunications to transmit information.

High frequency Definition & Meaning Dictionary.com

WebSo ground wave transmission is limited to a frequency of 1500 kHz. Q.70 Why sky waves are not used in the transmission of TV signals? Sol. TV signals have frequency much higher than 30 MHz. Such high frequency signals cannot be reflected by the ionosphere. Therefore, sky waves are not used in the transmission of TV signals. WebLimits. The frequency boundaries of the radio spectrum are a matter of convention in physics and are somewhat arbitrary. Since radio waves are the lowest frequency category of electromagnetic waves, there is no lower limit to the frequency of radio waves.
