Question

3) What happens to the loudness of a sound wave as you walk towards a sound source? Why? it will become louder because it is more intense Now choose from one of the following options Why? It becomes louder. This is because sound waves near the source have greater energy and greater amplitude bIt becomes less loud. This is because sound waves near the source have lower energy and amplitude. It becomes louder. This is because sound waves near the source have greater speed and intensity It becomes less loud. This is because sound waves near the source have lower speed and intensity d

Explanation / Answer

Option A is correct since near the source amplitude is greater and so its energy and intensity will also be greater but option C also includes speed which is not dependent upon distance so that is incorrect. As the distance increases waves of sound spread out and results in less intensity and lower amplitude and thus loudness will also decrease.
