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 heared easily. The sound X is used in hosphitals to break kidneys 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. (a) What type of sounds are (i) X (ii) Y, and (iii) Z? (b) Name one device which can produce sound like X. (c) Name one device in a science laboratory which can produce sound like Y. (d) Name one device in our homes which can produce sound like Z. (e) What is the frequency range of sounds like Z?
