Definitions

• Noun: The rate at which something occurs over a particular period; the number of times an event or action happens within a specific time frame. For instance: “The frequency of earthquakes in this region is quite high.”

  • In physics, it refers to the number of oscillations or waves per second, measured in hertz (Hz). For example: “The frequency of the sound wave determines its pitch.”
