Why do wind chimes make different tones?
Show answer & explanation
Answer: Each tube has different length
Each tube has different length ✓ — Correct! Wind chimes have tubes of different lengths. When struck, each tube vibrates at a frequency determined by its length—longer tubes vibrate slower (lower pitch), shorter tubes vibrate faster (higher pitch). Together they create a harmonious chord.
Metal composition varies per tube — Wrong. While different metals have different tones, the main pitch difference comes from tube length, not composition.
Clapper hits at different angles — Wrong. Striking angle doesn't significantly change pitch. The tube's length and physical properties determine the basic frequency it produces.
