Asked by Blaine

The speed of a note created by a flute will increase as the speed of sound increases. When a marching band goes outside on a cold day, pose a hypothesis as to what would happen to the note played on a flute.
Responses
A It would decrease because the speed of sound and temperature are proportional.It would decrease because the speed of sound and temperature are proportional.
B It would increase because the speed of sound and temperature are proportional.It would increase because the speed of sound and temperature are proportional.
C It would decrease because the speed of sound and temperature are inversely proportional.It would decrease because the speed of sound and temperature are inversely proportional.
D It would increase because the speed of sound and temperature are inversely proportional.

A. On a cold day the air temperature drops, which lowers the speed of sound (speed ∝ temperature). For a flute the resonant frequency f ∝ speed of sound, so the note's frequency (pitch) will decrease (sound flatter).
