Question

what is the CGS unit of amplitude

Answer 1

Any unit that measures distance can be used for measurement of amplitude. In SI system is unit is metre, same goes with MKS system, in CGS system is unit is centimetre and in the FPS system is unit is foot. The SI system is widely followed.

Answer 2

Answer:

Sound is another form of energy that travels in the form of waves either through a liquid, air, or even solid substances. Since this energy can be measured, the most common SI unit of sound that is used is Decibel which is abbreviated as dB.

This unit is basically used to express the ratio of some value of a physical property to another mainly on a logarithmic scale. This is called as Decibel Scale or DB Scale.

Moreover, the unit can be used to express different reference pressures or intensity. However, students have to make note that the sound intensity given in dB in the air will be different from dB in water.

Some Other Sound Units:

Some of the other sound units include:

sone

phon

Hertz (Hz)

watt per square meter (W/m2)

These units are used depending on what properties of sound we are dealing with. For example, sound intensity is measured in watt per square meter (W/m2).
