Distance between the peakes and troughs in a waves oscillations.
Decibels probably
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.
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.
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?"
