A bucket full of water hangs from one end of a string that passes over a light pulley. The other end of the string is driven by an ocillator of constant frequency, and the fundamental mode of standing waves is observed with one loop formed between the oscillator and the pulley. Holes are poked in the bucket causing it to start leaking water. When the bucket's mass drops to 1/4 of its initial value, Cscillator oscillator pulley pulley water-filled becket (m) leaking bucket (m'-m 4) No standing waves are observed on the string A standing wave with two loops is observed A standing wave with four loops is observed A standing wave with three loops is observed
