Order to reduce the loudness of a sound, we have to$(a)$. decrease its frequency of vibration of the sound$(b)$. increase its frequency of vibration of the sound$(c)$. decrease its amplitude of vibration of the sound$(d)$. increase its amplitude of vibration of the sound
The loudness of sound is determined by its$(a)$. amplitude of vibration$(b)$. ratio of amplitude and frequency of vibration$(c)$. frequency of vibration$(d)$. product of amplitude and frequency of vibration
Fill in the blanks with suitable words.$(a)$. Time taken by an object to complete one oscillation is called______.$(b)$. Loudness is determined by the ________ of vibration.$(c)$. The unit of frequency is _________.$(d)$. Unwanted sound is called _________.$(e)$. The shrillness of a sound is determined by the _________ of vibration.
