The following six (6) items consist of two statements, Statement I and Statement II. Examine these two statements carefully and select the correct answer using the code given below.
\nStatement I :
\nThe pitch of the sound wave depends upon its frequency.
\nStatement II :
\nThe loudness of the sound wave depends upon its amplitude.<\/p>\n

[amp_mcq option1=”Both the statements are individually true and Statement II is the correct explanation of Statement I” option2=”Both the statements are individually true but Statement II is not the correct explanation of Statement I” option3=”Statement I is true but Statement II is false” option4=”Statement I is false but Statement II is true” correct=”option2″]<\/p>\n

\nStatement I is true: The pitch of a sound wave is determined by its frequency; higher frequency corresponds to higher pitch. Statement II is also true: The loudness (intensity) of a sound wave is related to its amplitude; greater amplitude corresponds to greater loudness. However, these are two distinct properties of sound waves that are not causally related to each other in the sense that the mechanism determining loudness does not explain why pitch is determined by frequency.
\n<\/section>\n
\n– Pitch is the perceptual property that allows sounds to be ordered on a frequency-related scale, or more commonly, pitch is the quality that makes it possible to judge sounds as “higher” and “lower”.
\n– Loudness is the subjective perception of sound pressure. It is related to the intensity of the sound wave, which in turn is proportional to the square of the amplitude.
\n– Frequency and amplitude are independent physical characteristics of a wave.
\n<\/section>\n
\nWhile both statements correctly describe fundamental properties of sound waves, the fact that loudness depends on amplitude does not explain why pitch depends on frequency. Therefore, Statement II does not explain Statement I.
