Answer: Option (B) is the correct answer.
Step-by-step explanation:
The amplitude of a sound wave is proportional to the volume of sound. Hence, more is the volume more will be the amplitude of sound or vice versa.
For example, harder we strike a drum more will be its amplitude therefore, more will be its volume.
A substance through which wave travels from one point to another is known as a medium.
And number of waves that travel through a particular point is known as frequency. Whereas more rapidly a sound wave oscillates more will be its pitch.
Thus, we can conclude that the harder you strike a drum, the greater the sound’s volume.
