How do I solve?
When you blow across the top of a soda bottle, it acts like a closed pipe with a fundamental frequency of 495 Hz. If you pour 0.030 m of water into the bottle, shortening the air cavity, what is the new fundamental frequency? (Hint: Find the original length.)

You have two air columns that are each 2.130 m long. One column is open at both ends and the other is closed at one end. You wish to determine the frequencies you can produce in the audible range (20 Hz–20,000 Hz) on a day when the temperature of the air is at 22.00°C. (Give your answers to at least four significant figures. Assume that the speed of sound at 0° C is exactly 331 m/s.) (a) in the column that...

You have a string with a mass of 12.9 g. You stretch the string with a force of 9.19 N, giving it a length of 1.95 m. Then you vibrate the string transversely at precisely the frequency that corresponds to its fourth normal mode, that is, at its fourth harmonic. What is the wavelength of the standing wave you create in the string? What is the frequency? Wavelength? (m) Frequency? (Hz)
