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

Statement given below is incorrect. Write the correct statement. The time taken by a vibrating body to complete one vibration is called frequency.

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

What are damped vibrations ?

Sound can only be produced by vibrating bodies

A string fixed at both is vibrating in the lowest mode of vibration for which a point at quarter of its length from one end is a point of maximum displacement . The frequency of vibration emitted when it vibrates in the next mode such that this point is again a point of maximum displacement ?

Define resonant vibrations.

(a) Draw diagrams to show the longitudinal mode of vibration and transverse mode of vibration of an electrically maintained tuning fork in the Melde's experiment. (b) Indicate with the help of a diagram the positions of nodes and antinodes on a vibrating tuning fork.

The frequency of sound produced by a vibrating body in air is 15,000 Hz. Will the sound be audible to humans?

A string fixed at both ends, is vibrating in a particular mode of vibration. Vibration is such that a point on string is at maximum displacement and it is at a distance of one fourth of length of string from one end. The frequency of vibration in thus mode is 200 Hz . What will be the frequency of vibration when it vibrates in next mode such that the same point is at maximum displacement?

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