Tubes Quiz

For the tube on the far right, how many nodes does it have?

• 3

• 4

• 5

• 6

For the tube on the far left, how many antinodes does it have?

• 1

• 2

• 1/2

• 1/4

For the tube on the far left, what is the equation you would use to find the wavelength?

•  $\lambda$ = 2L

•  $\lambda$ = L

•  $\lambda$ = L/2

•  $\lambda$ = 4L

The order of the tubes is 1-2-3-4. For the 3rd tube, what is the correct formula for the wavelength?

From left to right, tube numbers are 1-2-3-4. For the 3rd tube, what is the harmonic number?

• 1st harmonic

• 2nd harmonic

• 3d harmonic

• 5th harmonic

Even numbered harmonics do not form in a closed pipe because

• the pipe “fits” only an odd number of quarter wavelengths

• the pipe “fits” only an even number of quarter wavelengths

• the pipe cannot put an anti-node at the open end

• the pipe cannot get enough air to vibrate in the pipe at these lengths
