Re: Can amplitude of sound wave exceed its wavelength?

Hello Simon

I'm not sure I really understand your question.  Waves are energy 
transport phenomena; they transport energy through a medium without 
transporting matter

Amplitude is a measurement of the intensity or energy of a wave.  A high 
energy wave has a large amplitude while a low energy wave has a low 
amplitude.  

In the case of sound, the amplitude of the wave would be a measure of 
loudness while wavelength would be more related to the pitch of the sound. 

Wavelength is simply the length of on complete wave cycle, for instance 
from crest to crest.

You may be confusing the frequency and the period of the wave.  Frequency 
is a measure of how often particles vibrate when a wave passes through 
them.  Mathmatically speaking, frequency is is the number of complete 
vibrational cycles of a medium per a given amount of time. Frequency is 
measured in cycles per second, or Hertz (Hz).  

The period refers to the time it takes to do something.  The period of a 
wave is the time for a particle on a medium to make one complete 
vibrational cycle and as such is measured in units of time; seconds, 
minutes etc.  

Period = 1/frequency  Frequency = 1/period

I hope this is helpful.
