A wave in which the particles of the medium vibrate back and forth in the 'same direction', in which the wave is moving, is called a longitudinal wave. These waves can be produced in all the three media: solids, liquids and gases.
A wave in which the particles of the medium vibrate up and down 'at right angles' to the direction in which the wave is moving, is called a transverse wave. It can be produced in solids and liquids but not in gases.

- 4Three 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
