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

You are watching: What happens to the period of a wave as the frequency increases?

In the text, you"ll also find the frequency definition, 2 frequency formulas (period come frequency and wavelength to frequency), and also a few examples showing exactly how to calculation frequency.

If you want to know much more about waves, inspect the wavelength calculator, and if you desire to recognize the frequency of music notes, check out the note frequency calculator.


Frequency an interpretation and the frequency formula


Have a look at the adhering to model that a wave; the will help you recognize the terms supplied in the frequency an interpretation below it.

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

This frequency an interpretation leads united state to the most basic frequency formula:

f = 1 / T.

f denotes frequency and also T stands for the time that takes to finish one wave cycle measure up in seconds.

The SI frequency unit is Hertz (Hz), which equals 1/s (one cycle per second). Various other frequency units incorporate millihertz (mHz), kilohertz (kHz), megahertz (MHz), gigahertz (GHz), and terahertz (THz).


Frequency equation indigenous the wavelength


Have a look at another photo which will enable us to see that frequency is associated to wavelength. Wavelength is the distance between two adjacent crests (or troughs). In other words - it is the size of one wave cycle. The much longer the wavelength, the lower the frequency:

*
Source: Encyclopedia Britannica) one more fact we need - how quick the waves take trip at (wave velocity) identify how many of them will certainly pass a given suggest per second. This means the higher the wave velocity, the greater the frequency.

These two relationships between frequency and also wavelength (λ), and also between frequency and velocity (v), bring us to the following frequency equation:

f = v / λ.


How to use the frequency calculator?


Our frequency calculator incorporates the above-mentioned frequency formulas, as such you have the right to use it together a duration to frequency calculator or a wavelength to frequency calculator.

How to use it together a period to frequency calculator? (How to uncover frequency if you understand period?)

Input the moment in i beg your pardon one tide cycle wake up (period). The calculator will recognize the frequency.

You deserve to use this calculator to recognize the period, if you recognize its frequency.

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

Enter the tide velocity right into the 2nd field or pick the kind of wave and also its tool from the list 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 can enter any type of two variables, and also the third will show up immediately
