▼

- The louder sound is produced by the guitar string that is plucked harder.
- This is because the amplitude of a wave is directly related to its loudness. When a string is plucked harder, it vibrates with a greater amplitude, resulting in a louder sound.
- In the diagram, the wave on the right has a larger amplitude (higher peaks and deeper troughs) compared to the wave on the left. Therefore, the wave on the right represents the louder sound.
- The wave on the left, with its smaller amplitude, represents the quieter sound produced when the string is plucked gently.

Parent Tip: Review the logic above to help your child master the concept of sound wave worksheet.
