Question
Give two examples each of longitudinal waves and transverse waves.
Advertisements
Solution
Examples of longitudinal waves are:
(i) The waves that travel along a spring when it is pushed and pulled at one end.
(ii) Sound waves in air.
Examples of transverse waves are:
(i) The waves produced by moving one end of a long spring up and down rapidly while the other end is fixed.
(ii) The water waves (or ripples) formed on the surface of water in a pond by throwing a stone in it.
