Earthquake produces which kind of sound before the main shock wave begins :

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?

Earthquake (shock) waves are

An earhquake generates both transverse (S) and logitudinal (P) sound wave in the earth .The speed of (S) wave is about 4.5km//s and that of (P) wave is about 8.0km//s A seimsograph records P and S wave fr5om an earthquake The first P wave arrives 4.0 min before the first S wave The epicenter of the earthpake is located at a distance of about

Earthwuakes generate sound waves inside the earth. Unilke a gas, the earth can experience both transverse (S) and longitudinal (P) sound waves. Typically, the speed of S wave is about 4.0 km s^(-1) , and that of P wave is 8.0 kms^(-1) . A seismograph records P and S waved from an earthquake. The first P wave arrives 4 min before the first S wave. Assuming the waves travel in straight line, how far away does the earthquake occur?

An earthquake generates both transverse (S) and longitudinal (P) sound waves in the earth. The speed of S waves is about 4.5 km /s and that of P waves is about 8.0 km/s . A seismograph records P and S waves from an earthquake. The first P wave arrives 4.0 min before the first S wave. The epicenter of the earthquake is located at a distance about

What kind of waves are sound waves produced in air ?

A sound wave travels 60m in the time taken to produce 50 waves. Find the wavelength of the sound wave in centimeters

The figure given below shows the images of sound waves. Look at them and answer the following questions Which two sounds were produced by the same instrument ?
