April 7 Welcome back Learning Target: Wind instruments use a standing wave inside a column of air. Vocabulary: 1. fundamental 2. open tube. 3. closed tube Agenda: Review any homework. Notes on wind instruments and Doppler effect Quiz Homework on wind instruments

Quiz on wind instruments and Doppler effect Fundamental Quality or timbre Rarefaction Destructive Waves appear to move further away. The lowest frequency standing wave is called What aspect of sound makes a “B” sound different on a flute vs a piano? In sound waves, a crest is a compression and the trough is ___________________. Two Speakers send out waves that will behave constructive at some points and _____________________at others. Why does pitch sound lower as an object moves away?
