Radio waves are made by various types of transmitter, depending on the wavelength. They are also given off by stars, sparks and lightning, which is why you hear interference on your radio in a thunderstorm. Pacific Waves Tv & Radio USA, Kent, Washington. 6.6K likes.

Radio waves and cellphone frequencies operate on different waves of the electromagnetic spectrum, measured in Hertz. A single Hertz cycles once per second. Radio broadcasting operates from 3 Hz to 300 kHz frequencies, while cellphones operate in narrower bands. In this video we cover:- How radio waves can be transmitted using oscilloscopes, transmitters, and receivers- How the transmission of radio waves can be used 2020-05-30 · Ionizing radio waves have the potential to cause sickness, burns, or cancer. Non-ionizing. Non-ionizing electromagnetic waves don’t carry enough energy in their photons to ionize or break the atoms and cells.

The broad category of radio waves is defined to contain any electromagnetic wave produced by currents in wires and circuits. Its name derives from their most common use as a carrier of audio information (i.e., radio).

The voltage in a radio wave alternates back and forth between plus and minus many times per second and we call this the frequency of the radio wave in cycles per second. WAVE Radio & WAVE TV, Belize City, Belize. 16,915 likes · 365 talking about this.

The benefits and drawbacks of blocking radio waves come in the form of either intentional or accidental events. 2020-04-09 · Radio waves are electromagnetic radiation, but they fall within the category of non-ionizing radiation, meaning they are longer and less energetic wavelengths. Studies on the effects of long-term and close-proximity exposure are still producing mixed results. These waves include AM and FM radio signals, and TV broadcasting signals." Here is a nice PDF introducing the concepts.
