Which of the following is correct about sound?
I. Large amplitude – Loud sound
II. High frequency – Low pitch
  • AOnly I
  • BNeither I nor II
  • COnly II
  • DBoth I and II
Correct answer: A

Loudness depends on amplitude (large amplitude – loud sound), so I is correct. Pitch depends on frequency, and high frequency means high pitch, not low pitch, so II is wrong. Only I is correct.
