When the amplitude of vibration is large, sound produced is
Loudness of a sound is proportional to the square of the amplitude of the vibration producing the sound. Explain
Question 3 (c) State whether the following statement is true or false. If the amplitude of vibration is large, the sound is feeble.
State whether the following statements are true or false:
(a) Sound cannot travel in vacuum.
(b) The number of oscillations per second of a vibrating object is called its time-period.
(c) If the amplitude of vibrations is large, sound is feeble.
(d) The lower the frequency of vibration, the higher is the pitch.
(e) If the amplitude of vibrations is doubled, the loudness of sound also gets doubled.
(f) When the amplitude of vibrations is halved, the loudness of sound becomes one-fourth.
(g) Unwanted or unpleasant sound is termed as music.
(h) Noise pollution may cause partial hearing impairment.
