Which of the following statements is correct?
(a) The time taken for one oscillation is the frequency.
(b) The distance covered by a vibrating body while making one complete oscillation is four times the amplitude.
(c) The greater the amplitude of a vibrating body, the higher will be the pitch of the sound it gives out.
(d) In a string instrument, thin strings are used for low pitch notes.

Solution

(a) False

The time taken for one oscillation is the time period.

(b) False

The distance covered by a vibrating body while making one complete oscillation is its wavelength.

(c) False

The greater the amplitude of a vibrating body, the louder will be the sound it gives out.
(d) False

In a string instrument, thin strings are used for high-pitch notes.
