- Which two waves represent sounds of the same loudness but different pitch$?$
- Which two waves represent sounds of the same frequency but different loudness?
- State whether all these sound waves have been produced by the same vibrating body or different vibrating bodies?
- Which vibrating body/bodies could have generated the sound waves shown here?

- $A$ and $D$ waves represent sounds of the same loudness but different pitch as both of them have same amplitude but different frequency.
- $B$ and $D$ waves represent sounds of same frequency but different loudness as both have same frequency but different amplitude.
- Same vibrating body can produce all the given sound waves.
- Tuning fork is a device that can produce sound waves of different frequencies and amplitudes. Therefore, all these sound waves can be generated by a tuning fork.

- 3A sound producing body is at considerable distance from a man. There can be four different media $W, X, Y$ and $Z$ between the sound producing body and the man. The medium $X$ brings the sound to man most quickly whereas medium $Z$ takes the maximum time. The time taken by medium $W$ in bringing sound to man is less than that of $X$ but more than that of $Z.$ The medium $Y,$ however, fails to bring the sound from the sound producing body to the man.

- 6Three different vibrating objects produce three types of sounds $X$, $Y$ and $Z$. Sounds $X$ and $Y$ cannot be heard by a man having normal range of hearing but sound $Z$ can be heard easily. The sound $X$ is used in hospitals to break kidney stones of a patient into fine grains whioch then get flushed out with urine. The sound $Y$ is similar to that which is produced during an earthquake before the main shock wave is generated.View Solution
