Sound Properties: Identify Incorrect Statement

Sound waves possess distinct characteristics, including amplitude and frequency. The amplitude generally relates to the perceived loudness of a sound, while the frequency relates to its pitch.

Statement Analysis

• Soft sound has small amplitude: Correct. Softer sounds have lower energy, which corresponds to a smaller wave amplitude.
• Loud sound has large amplitude: Correct. Louder sounds possess higher energy, indicated by a larger wave amplitude.
• Loudness depends on frequency: Incorrect. Loudness is primarily determined by the amplitude of the sound wave. Frequency is the characteristic that determines the pitch (highness or lowness) of a sound.
• Loudness depends on amplitude: Correct. The amplitude is the main factor influencing how loud a sound is perceived.

The question requires identifying the statement that is NOT correct. Based on the fundamental properties of sound waves, loudness is linked to amplitude, not frequency.
