Homework Statement
There is a plastic bottle into which we blow in such a way, that we receive a sound of freguency f. The bottle is filled with water that has volume V. Prove, that [tex]f=f_{0}(\frac{V}{V_{0}})^{\alpha}[/tex], where [tex]f_{0}, V_{0}, \alpha[/tex] are constants.
Homework Equations
The Attempt at a Solution
I always thought, that the wavelength is directly proportional to height of an empty part of the bottle, but then f is inversely proportional to V. Is there any mistake in this task?
