Ethan investigated how the pitch of a sound changes with the length of a vibrating string. He used strings of different lengths (10 cm, 20 cm, 30 cm) on a simple musical instrument and measured the pitch of the sound produced.
Using the graph, describe the relationship between string length and pitch (Hz).
Which statement is best supported by the data?
Using specific data from the graph, explain how the pitch changes between 10 cm and 30 cm strings.
How does changing the length of the string change the structure of the vibrating system, affecting the sound produced?
Which conclusion is best supported by the investigation?
A student claims: “Shorter vibrating strings produce higher-pitched sounds because they vibrate faster.” Do you agree or disagree?
Claim:
Evidence:
Reasoning:
