If you sit on it, you will feel it bunch up and spread out underneath you. Time how long it takes between bunchings. This time is called the period. You may need to remove your trousers for a more sensitive measurement.
You also need to measure how fast the wave is travelling. Sit sideways on it, and time how long it takes between a bunching under one buttock and then under the other. This time is the interbuttock consecutive excitation interval. Take the reciprocal, and multiply by your interbuttock separation distance (which you can get from your doctor). The result is the wavespeed.
Now, all you need to do is multiply the period by the wavespeed, and the answer will be the wavelength.
This question cannot be answered - without at least some data to calculate !
wave length = wave speed divided by its frequency
Wavelength*Frequency = Velocity of the wave. or Wavelength/Period = Velocity of the wave.
speed= frqquency*wavelength
draw a triangle and make 3 areas in the triangle. on the top is S or Speed. on the bottom left is F or Frequency. and on the bottom right is a bckwards/upside down Y for Wavelength. then S divided by For Y. and F times Y. will get you wavelength and what you need. draw what i just said.
It depends on the wavelength and frequency of the wave.
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.
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
Sound waves are longitudinal in nature, and they require a medium for propagation.
You can find it the same way you would for most other waves, with the formula of v=fλ (velocity = frequency x wavelength)
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
Longitudinal waves have all the same properties as transverse waves: speed, frequency, wavelength, and amplitude
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.
To get the wavelength of a wave simply divide the wavespeed with its frequency.
