If the vibrations of a vibrating body are fast then the sound is said to be high-pitched. (True or False)

The number of vibrations made by a vibrating body in one second is called :

Define frequency of a vibrating body. Write its Sl unit.

Define amplitude of a vibrating body. What is its SI unit?

If we study the vibration of a pipe open at both ends, then the following statements is not true

The time period of a vibrating body is 0.020. What is its frequency?

You will always be able to see vibrations in an object. (True or false)

The diagram in Fig. shows the displacement time graph of a vibrating body. What happens to the vibrations of the body after some time?

Every particle in a longitudinal wave only vibrates about a fixed position. It does not move from its position with the wave(True or false).

The diagram below shows the displacement-time graph for a vibrating body. Name the type of vibrations produced by the vibrating body.
