the speed of light and all electromagnetic waves in a vacuum is 300,000,000 m/s or 3×10 8 m/s the speed of sound in air is often taken to be 340 m/s.

Amplitude modulation (AM) is also widely used to alter a carrier wave to transmit data. For example, in AM radio, the voltage (amplitude) of a carrier with a fixed center frequency (the station's ...

It is also the time taken for one whole wave to pass a point. Period is measured in seconds. All waves, including sound waves and electromagnetic waves, follow this equation. It should be noted ...
