Consider the following sound waves marked A, B, C and D:

(a) Which two waves represent sounds of the same loudness but different pitch?


(b) Which two waves represent sounds of the same frequency but different loudness?


(c) State whether all these sound waves have been produced by the same vibrating body or different vibrating bodies?


(d) Which vibrating body/bodies could have generated the sound waves shown here?

(a) A and D are two sund waves which represent sounds of the same loudness but different pitch.

(b) B and D are two waves which represent sounds of the same frequency but different loudness.


(c) All these sound waves have been produced by the same vibrating body.


(d) Tuning forks could have generated the sound wave shown here.
