The time taken by a particle in reaching from trough to crest in a transverse wave is Correct Answer T/2

CONCEPT:

Transverse wave

Longitudinal wave

Transverse waves can propagate in solid as well as in a liquid.

Longitudinal waves can propagate in solid, liquid and gases.

The transverse wave consists of trough and crest.

It has compression and rarefaction.

It doesn’t have the pressure variation

It can have the pressure variation.

It doesn’t change its medium.

There is a change in density throughout the medium.

A lightwave is an example of a transverse wave.

A soundwave is an example of a longitudinal wave.

  • For a wave with time period T, trough to crest means reaching from one extreme to another.
  • Therefore, the time taken is half of the time period, if we observe it as a sinusoidal wave. Hence option 3 is correct.

A Time taken by pipe P and Q to fill the tank is 120/23 minutes. Time taken by drain pipe S to empty the tank is 12 minutes more than pipe P to fill the tank. Time taken by pipe Q is 15 minutes.
