What is the lowest frequency of the sound wave

Reference no: EM13561656

Throughout the problem, take the speed of sound in air to be 343 .
Part A
Consider a pipe of length 80.0 open at both ends. What is the lowest frequency of the sound wave produced when you blow into the pipe?
Express your answer in hertz.
Part B
A hole is now drilled through the side of the pipe and air is blown again into the pipe through the same opening. The fundamental frequency of the sound wave generated in the pipe is now
the same as before.
lower than before.
higher than before.
Part C
If you drill a hole at a position half the length of the pipe, what is the fundamental frequency of the sound that can be produced in the pipe?
Express your answer in hertz.
Part D
What frequencies can you create when blowing air into the pipe that has a hole halfway down its length?
Only the odd multiples of the fundamental frequency
Only the even multiples of the fundamental frequency
All integer multiples of the fundamental frequency
Part F
What is the frequency F_n of the first possible harmonic after the fundamental frequency in the open-closed pipe described in Part E?
And here is part E
Part E
What length of open-closed pipe would you need to achieve the same fundamental frequency as the open-open pipe discussed in Part A?
a. Half the length of the open-open pipe
b. Twice the length of the open-open pipe
c. One-fourth the length of the open-open pipe
d. Four times the length of the open-open pipe
e. The same as the length of the open-open pipe
