It seems to me that pulse amplitude simply describes amplitude and then adds "...of a pulse". TomViza 09:47, 29 January 2007 (UTC)
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. SURE>>>>>
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.
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?
I don't think it should be added on. It may be a similar and very short definition, but it's still different from amplitude.

hii this is jot..sorry i did t get any information about amplitude...the given information is very differant i think what type of my book information so plzz give me some detail —Preceding unsigned comment added by 122.109.55.87 (talk) 07:14, 23 March 2009 (UTC)
When most people refer to amplitude, they are implicitly talking about peak to peak amplitude, not rms. So I think we should mention that the term amplitude, when used without any qualifiers, is referring to peak to peak. Any comments? —Preceding unsigned comment added by 131.183.23.225 (talk) 21:21, 15 September 2009 (UTC)
In electricity, the current meaning of amplitude concerns the voltage caracteristic of a signal.
Question : Could one speak of amplitude of the intensity caracteristic ? In this case an amplifier (see amplifier page) could be an intensity amplifier ! But in current usage an amplifier is a voltage amplifier. Any ideas ?

"Semi-amplitude...is important in the search for exoplanets."
True or not, this is out of place, given that this is the only application that is exemplified. It makes the article read more like a wiki than an encyclopedia. 67.9.166.98 (talk) 05:55, 20 June 2010 (UTC)
Is the amplitude of a sound wave the difference between its equilibrium pressure and the local pressure within the oscillation? From what I remember, I was always taught that the amplitude of any wave is the distance that a PARTICLE is displaced while the wave is passing. Just wanted to confirm. —Preceding unsigned comment added by 72.73.162.32 (talk) 07:03, 27 July 2010 (UTC)
(in "Formal Representation" section) Surely it should be A*sin(ωt-k) + b ? Harveybrown51 (talk) 19:19, 3 December 2011 (UTC)
Good articles are written so that laymen/women with some intelligence, but without a specialist background, can understand them. This article has been written and maintained by people with no idea how to translate scientific terminology into ordinary language that someone without a scientific background can understand. To use this sort of plain language, "It stinks." Tapered (talk) 03:09, 15 September 2015 (UTC)
I'm searching the internet for a definition. You'd think this article would explain it. 2600:8801:BE31:D300:350B:FC57:5D61:625E (talk) 04:33, 23 July 2022 (UTC)
The intro states that amplitude measures the change in a periodic vairable in "a single period", wouldn't the change in a period be zero? It starts off at some point then returns to that point. Wouldn't it be more accurate to say it measure displacement from equilibrium or something? Sunny642 (talk) 14:05, 6 May 2023 (UTC)
