Question

which of the sound waves (i) or (ii) is louder and why
​

Answer 1

Answer:

Hi

Explanation:

The intensity or loudness of a sound depends upon the extent to which the sounding body vibrates, i.e., the amplitude of vibration. A sound is louder as the amplitude of vibration is greater, and the intensity decreases as the distance from the source increases. Loudness is measured in units called decibels.
