a. amplitude
b. compression
c. intensity
d. frequency

Answer 1

The correct option is C i.e intensity. The intensity of a sound wave is defined as the amount of energy passing through a unit area of the wavefront in a unit of time. It is denoted by I It is the measurement of the sound power at a particular location..It is also known as acoustic intensity.

Answer 2

The appropriate response to the question is intensity. Sound power otherwise called acoustic force is characterized as the Energy conveyed by the sound waves per unit zone. The SI unit of force, which incorporates sound power, is the watt per square meter
