Lakhmir Singh and Manjit Kaur Solutions for Chapter: Sound, Exercise 30: Questions Based on High Order Thinking Skills (HOTS)

Three 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 which 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. What type of sound is $Y$?
