Question

The amount of work done to produce a sound determines which property of sound waves?

A. frequency
B. wavelength
C. pitch
D. amplitude

Answer 1

The answer is D) Amplitude

Answer 2

Intensity of sound is defined by

`Intensity = (Energy)/(Area* time)`

So here we can say work done by us is stored in the form of energy of sound and that energy can be compared by the intensity of sound

So if we will do more work then the sound will have more energy and hence it will have more intensity

Now we know that intensity of sound is given as

`intensity = kA^2`

so more is the intensity then more work which means the amplitude will be more

So answer will be

D. amplitude
