Best Answer

Use the formula

f = v λ

Where f is frequency, v is the speed of the wave, and λ is the wavelength.

Dividing both sides by v gives

λ = f / v

What sound does a longitudinal wave make?

It depends on the wavelength and frequency of the wave.


What are the characteristics of sound waves?

The characteristics of a sound wave is the Amplitude, Frequency, Wavelength, time period, and velocity. The sound wave itself is a longitudinal wave that shows the rarefactions and compressions of a sound wave.


What wave type is a sound wave?

Sound waves are longitudinal in nature, and they require a medium for propagation.


How is wave length determined for a longitudinal wave?

You can find it the same way you would for most other waves, with the formula of v=fλ (velocity = frequency x wavelength)


How does one measure the wavelength of a longitudinal wave?

Okay, it is very simple. The formula is: the velocity is equal to the product of the frequency and wavelength. v= fλ the lambda is the wavelength. Using basic arithmetic, you can rearrange the equation to : λ= v/f There you go. That's how to find the wavelength


Which properties does a longitudinal wave lack?

Longitudinal waves have all the same properties as transverse waves: speed, frequency, wavelength, and amplitude


What is the distance from crest to midpoint of a transverse wave?

If I understand the question correctly, that's one-quarter of a full cycle, so it is 1/4 of the wavelength. The wavelength varies from wave to wave - and this has nothing to do whether the wave is transverse or longitudinal.


How do you find the wavelength of a wave?

To get the wavelength of a wave simply divide the wavespeed with its frequency.


Which term describes the distance between any two crests in a transfer wave or the distance between any rarefaction in a longitudinal wave?

Wavelength


Which term describes the distance between any two crests in transverse wave or the distance between any rarefactions in a longitudinal wave?

wavelength


A longitudinal wave with a wavelength of 0.57 meter has a period of 0.25 second. How far does the wave travel in 33 seconds?

It travels 2.28 metres.


What is the wavelength of an object?

The wavelength of a signal is calculated by c/f. C is the velocity of the wave and f the frequency of the signal. Wavelength is defined as the distance between any two successive crests or troughs in case of a mechanical wave. In case of longitudinal wave, the distance between two successive compressions or rarefactions will be the wavelength. In case of electromagnetic wave c/f will be the wavelength
