That depends on what discipline you're studying.
In Physics: the maximum extent of a vibration or oscillation, measured from the position of equilibrium.
• the maximum difference of an alternating electrical current or potential from the average value.
In Astronomy: the angular distance of a celestial object from the true east or west point of the horizon at rising or setting.
In Mathematics: the angle between the real axis of an Argand diagram and a vector representing a complex number.
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.
The amplitude is 1.
That if the original amplitude was A then it is now 2*A.
Amplitude is just themaximum displacementof a wave:
The amplitude is ' 1 ' .

The height of a wave is also known as its amplitude. More generally, the amplitude is "how much some measurement changes" - this measurement need not always be a height.
Distance between the peakes and troughs in a waves oscillations.
The trough of a wave appears to have a negative amplitude. However, because amplitude is a distance measurement, which is a scalar quantity having only magnitude, it has no sign.
You don't. Hz (always capitalized) is the unit for measuring frequency or pitch. dB is the unit for measuring amplitude or relative loudness of the sound. You cannot convert a frequency measurement to an amplitude measurement.
measurement of the amplitude of the largest seismic waves
Amperes Hertz Watts
a device called a rictor scale is used
The vertical distance between a wave's midpoint and its crest or trough is called is peak amplitude. This differentiates this measurement from the vertical distance from a crest to a trough, which is called its peak-to-peak amplitude.
We need a length or distance measurement here. The unit is meter or a part of it, like centimeter, millimeter.

Loudness is determined by the amplitude of the sound waves.
