A pipe that is open at both ends has a fundamental frequency of 330 Hz when the speed of sound in air is 333 m/s.
What is the length of this pipe? Answer in units of cm.
What is the second harmonic?
What is the third harmonic? Answer in units of Hz.
What is the fundamental frequency of this pipe when the speed of sound in air is increased to 363.9 m/s due to a rise in the temperature of the air? Answer in units of Hz.

bobpursley,
find lambda. Then the length of the pipe is lambda/2
