[edit] Merge

It seems to me that pulse amplitude simply describes amplitude and then adds "...of a pulse". TomViza 09:47, 29 January 2007 (UTC)

[edit] Why?

Hmm, it's really not a great idea to use y to mean two different things, in one short article. Can we either have a different variable for the simple wave equation (which anyway needs its terms explained), or change the diag? cheers, JackyR 08:39, 18 February 2006 (UTC)

y stands for the amplitude and the displacement, but in the diagram they're the same thing.

[edit] "maximum disturbance"

The artical states that "Amplitude [is the] ... maximum disturbance ..." but "maximum" suggests "from peak to trough" whereas it is actually from distance from the average or centre y position to the peak OR trough (as the diagram correctly shows). Can this wording be improved without futher complicating the statement.

A disturbance is the movement of something away from its normal or optimum configuration, so the maximum distrubance is the distance from the average or centre. The peak and trough are both "disturbed" states, while for many systems the center is the equilibrium point.--Srleffler 17:33, 28 March 2006 (UTC)

Why is Photon Energy proportional to frequency, and not Amplitude ? It seems to me that when a wave disturbance is produced in any medium, the amount of force over time (hence work) would register as an increase in AMPLITUDE of the wave disturbance at that point, as opposed to an increase in FREQUENCY. So why, in electromagnetic waves such as photons, is the formula E = h * v (frequency), and amplitude has nothing to do with it  ?

This article is very verbose, can we have someone clean it up so it is more accessible to someone who just needs a quick reference?
