Final answer:
Sound depends on two properties: pitch and loudness.
Step-by-step explanation:
Sound depends on two properties: pitch and loudness.
Pitch refers to how high or low a sound is and is determined by the frequency of the sound wave. Higher frequency waves have higher pitches, while lower frequency waves have lower pitches. For example, a high-pitched sound could be a whistle, while a low-pitched sound could be a bass drum.
Loudness refers to how soft or loud a sound is and is determined by the amplitude of the sound wave. Larger amplitude waves produce louder sounds, while smaller amplitude waves produce softer sounds. For example, a whisper would be a soft sound, while a firework explosion would be a loud sound.
