Compute all parts of following problem:
Problem: The frequency of the fundamental of an open cylindrical tube in air is 240 Hz. The frequency of the fundamental is 300 Hz when the same tube is placed inside a large container filled with an unknown gas.
Part A: Does the wavelength of the fundamental depend on what kind of gas is inside or around the tube?
Part B: What is the speed of sound in the unknown gas?
Please show all work and steps to determine the speed of sound in the unknown gas.
