Homework Statement
A metal rod attached to a tube with both closed ends is stimulated to create waves inside the tube.
If:
L = 1.0 m
d = 0.05 m
Speed of sound in air = 340 m/s
Speed of sound in metal = 1,000 m/s
Calculate the value of x using the wavelength of air.
Homework Equations
Frequency = Velocity / Wavelength
The Attempt at a Solution
The frequency of the the metal is the same as the frequency in air, so:
1,000 / (2*1.0) = 340 / wavelength of air
Because the wavelength of the metal is 2 * L.
340 / 500 = wavelength of air
0.68 = wavelength of air
How do I calculate wavelength with only the distance between two nodes (d)? I need x from wavelength according to the problem's instructions so I have to work backwards but I don't know any formulas for this one.
