Q. Consider the following statements regarding the properties of sound:
  1. Low pitch sound has low frequency, whereas high pitch sound has high frequency.
  2. Soft sound has small pitch, and louder sound has large pitch.
Which of the above statements is / are correct?

Answer: Only 1
Notes: Statement 1 is correct: pitch is directly related to the frequency of sound waves; low pitch corresponds to low frequency and high pitch to high frequency. Statement 2 is incorrect: softness and loudness depend on amplitude, not pitch. Thus, soft or loud sounds may have any pitch based on their frequency, not their amplitude.
