Question

Part 1
A spaceships lands on a new planet. The crew decides to measure the speed of sound in the atmosphere. Taking a tube with a length of 50 cm, they find that one resonant freqency occurs at 2,520 Hz, and the next resonant frequency at 2,940 Hz. What is the speed of sound? What is the number of each harmonic? What type of pipe is the crew using (open-open, closed-closed, or open-closed ended)?

Part 2
The crew from part 1 lands on another planet and repeat the experiment. This time they find frequencies of 1,620 Hz and 1,980 Hz. What is the speed of the sound? What is the number of each harmoic? What type of pipe is the crew using this time (open-open, closed-closed, or open-closed ended)?

Explanation / Answer

1) 330 m/s , 2 harmonics, open-closed
