How do you measure radio waves

WebA radio wave is just a type of electromagnetic wave, having a large wavelength and high frequency. A sound that is to be transmitted is created and converted into an electrical signal. Since this signal is not very strong, the signal is amplified with an amplifier. The signal now has a greater amplitude, making it stronger. WebOct 21, 2024 · To measure radioactivity, use a device that counts the number of subatomic particles emitted by a radioactive substance. The standard unit for this measurement is called the becquerel (Bq), which is equal to 1 particle, or count, per second. [10]
