Question
Distinguish between longitudinal and transverse waves.
✓

Answer

Longitudinal wave: 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.
Transverse wave: 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.

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 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.
