Pro Tip 1/2Wave Motion
Understand 'amplitude' as the height from the center line to the peak of a wave.
A loud sound has a higher amplitude compared to a whisper.
Pro Tip 2/2Amplitude Decrease
In motion, 'amplitude' can decrease over time due to factors like friction or resistance.
The amplitude of the swings lessened as the air resistance slowed them down.

but essentially what's happening here -- -- is the energy from the sound via the air and gas molecules is influencing the combustion properties of propane, creating a visible waveform, and we can see the alternating regions of compression and rarefaction that we call frequency, and the height is showing us amplitude.

For example, when you play two notes whose frequencies are close together, they add together to create a sound wave whose amplitude rises and falls, producing a throbbing effect, which guitarists call the beats. And electric guitars give you even more to play with. The vibrations still start in the strings,

to the loudest sound that you can stand -- say, a jackhammer or a jet plane. The amplitude of sounds spans a range of one millionfold, which is more than is encompassed by any other sense or by any man-made device of which I'm aware. And again, if this system deteriorates,

we effortlessly change notes as we speak. By pushing air faster or slower, we change the frequency and amplitude of these vibrations, which respectively translate to the pitch and volume of our voices. Rapid and small vibrations create high-pitched, quiet tones,

It changes with temperature and with barometric pressure. Now, imagine, if you will, without getting too technical, I'm making a little sine wave here in the air. Well, if I turn up the amplitude too much, I'm having an effect on the pressure,

So, the same is true of gravitational waves. We can't use them to make simple images of things out in the Universe. But by listening to changes in the amplitude and frequency of those waves, we can hear the story that those waves are telling.

we saw, in both detectors, a gravitational wave. In both detectors, we saw a signal with cycles that increased in amplitude and frequency and then go back down. And they were the same in both detectors. They were gravitational waves.

These gamma oscillations when they are seen in normal human beings are typically very, very brief. Less than one second in duration and we observe them continuously at high amplitude in these long-term meditation practitioners.

Richard P. Feynman
American Physicist
If we have an atom that is in an excited state and so is going to emit a photon, we cannot say when it will emit the photon. It has a certain amplitude to emit the photon at any time, and we can predict only a probability for emission; we cannot predict the future exactly.

Seth Shostak
American Scientist
There's no doubt that the Moon is more than a handy night light and a hair restorer for werewolves. It's responsible for the substantial amplitude of earthly ocean tides. These are of obvious influence if you're a geoduck, a type of clam that people dig up at low tide.
Quote examples
Rainer Weiss
American Physicist
The obvious thing to me was, let's take freely floating masses in space and measure the time it takes light to travel between them. The presence of a gravitational wave would change that time. Using the time difference, one could measure the amplitude of the wave.

I love the leisurely amplitude, the spaciousness, of taking a walk, of heading somewhere, anywhere, on foot. I love the sheer adventure of it: setting out and taking off.

As most who have engaged in competitive sports know, there's nothing to match the amplitude of emotion brought by losing.
