The frequency calculator will certainly let girlfriend find a wave"s frequency provided the wavelength and its velocity or period in no time. Friend can choose a tide velocity from the preset list, so girlfriend don"t need to remember, e.g., the speed of sound.

You are watching: As the period of a wave increases the frequency increases

In the text, you"ll likewise find the frequency definition, two frequency formulas (period come frequency and wavelength to frequency), and a couple of examples showing just how to calculate frequency.

If you desire to know an ext about waves, check the wavelength calculator, and if you desire to understand the frequency of music notes, check out the keep in mind frequency calculator.


Frequency an interpretation and the frequency formula


Have a look in ~ the following model of a wave; it will assist you recognize the terms provided in the frequency meaning below it.

*
Source: Encyclopedia Britannica Frequency is the number of completed tide cycles every second. In other words, frequency tells us how plenty of wave crests pass a given point in a second.

This frequency definition leads us to the simplest frequency formula:

f = 1 / T.

f denotes frequency and also T stands for the time the takes to complete one tide cycle measure up in seconds.

The SI frequency unit is Hertz (Hz), which equates to 1/s (one cycle per second). Other frequency units encompass millihertz (mHz), kilohertz (kHz), megahertz (MHz), gigahertz (GHz), and also terahertz (THz).


Frequency equation native the wavelength


Have a look at another snapshot which will allow us to check out that frequency is connected to wavelength. Wavelength is the distance in between two adjacent crests (or troughs). In other words - that is the length of one tide cycle. The longer the wavelength, the reduced the frequency:

*
Source: Encyclopedia Britannica) an additional fact we require - how rapid the waves travel at (wave velocity) identify how numerous of them will certainly pass a given allude per second. This method the greater the tide velocity, the greater the frequency.

These 2 relationships in between frequency and also wavelength (λ), and also between frequency and also velocity (v), bring us come the adhering to frequency equation:

f = v / λ.


How to use the frequency calculator?


Our frequency calculator incorporates the above-mentioned frequency formulas, thus you have the right to use it together a period to frequency calculator or a wavelength come frequency calculator.

How to usage it together a period to frequency calculator? (How to discover frequency if you know period?)

Input the time in which one wave cycle occurs (period). The calculator will identify the frequency.

You can use this calculator to determine the period, if you know its frequency.

How to use it as a wavelength to frequency calculator? (How to calculation frequency indigenous wavelength?)

Enter the wave velocity into the second field or pick the form of wave and its tool from the perform in the first field. Through default, the is collection to light in a vacuum.

Enter the wavelength, and also the frequency value will appear.

So, basically, you have the right to enter any kind of two variables, and also the 3rd will appear immediately
