"A tuning fork with a frequency of 440 Hz is held above a resonance tube partially filled with water. Assuming that the speed of sound in air is 342 m/s, for what heights of the air column will resonances occur?"
f1 = 440 Hz
v = 342m/s
I'm not sure if this is referring to an open pipe, or a closed pipe.
For an open pipe,
fn = (nv)/(2L) = nf1
v/(2L) = f1
L = v/(2f1)
L = 0.3886 m
But this is the length for the sound traveling up and down... i think. So the length is 0.194m. However, the answer gives 3 values, 0.194m, 0.583m, 0.972m. Even for a closed pipe, I there is only 1 value...
I must be doing something wrong. I don't think the speed of sound in water is a factor, because my first answer seems to be correct...
