Question

Which attribute of a sound wave is related to the loudness of sound?

  1. A. Amplitude (Correct answer)
  2. B. Frequency
  3. C. Pitch
  4. D. Speed

Correct Answer

Option A — Amplitude

Detailed Solution & Explanation

The correct answer is Amplitude.

Key Points

  • The loudness (intensity) of a sound wave is determined by its amplitude — the maximum displacement of particles from their rest position.
  • Greater amplitude means more energy in the wave and louder sound.
  • Frequency determines pitch (how high or low a sound is), while speed depends on the medium.
