Final answer:
There are five terms commonly used in radio transmissions: frequency, amplitude, modulation, antenna, and carrier wave. These terms are used by radio technicians, broadcasters, and anyone involved in radio communications.
Step-by-step explanation:
When making a transmission over the radio, there are several terms that are commonly used. Here are five of them:
- Frequency: This refers to the number of oscillations of the radio wave per second and is measured in Hertz (Hz). It determines the pitch of the sound or the channel on which the radio station broadcasts.
- Amplitude: This refers to the height of the radio wave and determines the volume of the sound.
- Modulation: This refers to the process of varying a characteristic of the radio wave, such as frequency or amplitude, to carry information. It is used to transmit the audio signal.
- Antenna: This is the device that sends and receives radio waves. It converts electrical signals into radio waves for transmission and vice versa.
- Carrier wave: This is a pure radio wave at a specific frequency that is modulated to carry the audio signal.
These terms are used by radio technicians, broadcasters, and anyone involved in radio communications.
