frequencies
1
the specific number of waves that pass a point every second
Frequency refers to the number of times a wave or signal repeats in a given period, typically measured in cycles per second or Hertz (Hz). In the context of radio, television, or other electromagnetic waves, frequency determines the type of wave and its ability to carry data. For example, higher frequencies, like those in the gigahertz range, are used for things like Wi-Fi and mobile networks, while lower frequencies are often used for AM and FM radio. The frequency of a signal impacts its range, clarity, and how it interacts with the environment.
- In physics, frequency is measured in hertz, which represents the number of waves passing a point per second.
- The frequency of the sound waves determines the pitch of the sound.
- The radio station broadcasts at a frequency of 101.5 megahertz.
- Higher frequencies of light, such as ultraviolet and X-rays, have shorter wavelengths.
