A measure of the strength of a wave is its amplitude which is the vertical distance between the heights of the wave's peaks and the heights of its troughs. An ocean wave might be said to be 20 metres high, for instance, meaning that an observer can see that the bottom of the wave is 20 metres below the top of the wave. The amplitude of that wave would be 20 metres.
If you wanted to compare two waves you could use their amplitude ratio, simply the ratio of their two amplitudes.

How do you determine the ratio of an amplitude?
Amplitude ratio to dB conversion:For amplitude of waves like voltage, current and sound pressure level:GdB = 20 log10(A2 / A1)A2 is the amplitude level.A1 is the referenced amplitude level.GdB is the amplitude ratio or gain in dB.dB to amplitude ratio conversion:A2 = A1 · 10(GdB / 20)A2 is the amplitude level.A1 is the referenced amplitude level.GdB is the amplitude ratio or gain in dB.
What is the amplitude of y equals sin x?
The amplitude is 1.
The amplitude of a pendulum is doubled this means?
That if the original amplitude was A then it is now 2*A.

What is depth of modulation?
In amplitude modulation, modulation depth refers to the ratio of the unmodulated carrier amplitude to the amplitude deviation for which the modulated carrier wave reaches its minimum value. If this minimum value is zero, the modulation depth is 100%.For amplitude modulation,modulation depth = (a-b)/(a+b),wherea is the unmodulated carrier amplitude, andb is the minimum amplitude deviation.The modulation depth ratio is also referred to as the modulation index.

What is max magnification of afm?
Its the ratio between laser deflection amplitude at detector to vibration of cantilever. Shamial
What is reflection coefficient?
The reflection coefficient is used in physics and electrical engineering when wave propagation in a medium containing discontinuities is considered.A reflection coefficient describes the amplitude of a reflected wave relative to that of the incident wave.In telecommunications, the reflection coefficient is the ratio of the amplitude of the reflected wave to the amplitude of the incident wave.
A sound waves amplitude corresponds to the sounds what?
Usually, people are asking as if there is just "the" amplitude in sound waves in air. The loudness perception of a sound is determined by the amplitude of the sound waves − the higher the amplitude, the louder the sound. Which amplitude of sound (sound amplitude) do you mean? There are: amplitude of particle displacement ξ, or displacement amplitude amplitude of sound pressure p or pressure amplitude amplitude of sound particle velocity v, or particle velocity amplitude amplitude of pressure gradient Δ p, or pressure gradient amplitude. Furthermore, think of the amplitude of the oscillation of a string. The maximum magnitude of the deflection of a wave is called amplitude. Look at link: "What is an amplitude?"
How are the amplitudes of sound waves?
There is not only "one" amplitude. There is an amplitude of particle displacement ξ, or displacement amplitude, an amplitude of sound pressure p or pressure amplitude, an amplitude of sound particle velocity v, or particle velocity amplitude, an amplitude of pressure gradient Δ p, or pressure gradient amplitude. If the "sound" inceases, the "amplitude" also increases.
What is maximum displacement of the wave from equilibrium called?
The term for maximum displacement is the amplitude of the wave.
How do the amplitude of a 120 - decibel sound and a 100 - decibel sound compare?
-- A difference of 20 dB means the louder one is delivering 100 times as much power as the softer one is. -- The power delivered by any sinusoidal phenomenon is usually proportional to the square of the amplitude. So the amplitudes would have to be in the ratio of 10 to 1. The louder one has 10 times the amplitude of the softer one.
Why you calculate percentage modulation?
For AM (amplitude modulation) signals, it is the ratio (x100 of course) of the modulating signal to the carrier signal. presumably FM calculations follow a similar course.
What happens to the frequency and Amplitude when you scream?
amplitude increases (louder the sound is, bigger is the amplitude)
When signal amplitude is equal to carrier amplitude then modulation index is?
amplitude modulating signal
