Striking a drum harder or softer produces sound that differs in:
Amplitude
Time period
Frequency
Periodicity
Striking a drum harder or softer, results in change in the loudness of the sound but not the frequency. Hence the amplitude of the sound changes.
What are wavelength, frequency, time period and amplitude of a sound wave?
Clsssify the sound produced by the following on thhe basiis of higher amplitude and higher frequency:-
_ drum
_roaring of lion
_whistle
-guitar
_chirping of birds
(a) What differences will you hear in a sound if there is an increase in (i) amplitude, and (ii) frequency?
(b) Calculate the time period of a pendulum which is vibrating with a frequency of 10 Hertz.
