# Frequency

The number of times an alternating current reverses direction per second is called frequency. The standard unit of frequency is the hertz (Hz), which is equal to one cycle per second. What is frequency give an example? Frequency refers to the number of times a particular event occurs over a specified period of time. For example, if a light is flashing once every second, its frequency would be 1 Hz.

#### What is frequency in wave?

Frequency is the number of complete waves that pass a given point in a specified amount of time. It is usually expressed in units of waves per second, or hertz (Hz). The frequency of a wave is related to its wavelength by the equation:

f = v/λ

where f is the frequency, v is the velocity of the wave, and λ is the wavelength. What is another word for frequency? The word "frequency" is used to describe the rate at which something occurs. In the context of electronics, frequency can refer to the rate at which a signal oscillates, or the number of times a particular event happens within a given time period. What is the unit of frequency? The unit of frequency is the hertz (Hz), which corresponds to the number of cycles per second.

##### How is frequency measured?

There are a few different ways to measure frequency, but the most common method is to use an oscilloscope. This device measures the voltage of a signal and displays it as a waveform on a screen. By measuring the time it takes for the waveform to complete one cycle, the frequency can be calculated.
