Homework Statement
A tube closed at one end and open at the other has a fundamental frequency of 242 Hz. What is the fundamental whenboth are open?
Homework Equations
f (open and closed) = v/4L
f (open) = v/2L
v sound = 343 m/s
The Attempt at a Solution
f1 (open and closed) = v/4L = 242Hz = 343/4L
L = .354 m
f (open) = v /2L = 343/ 2(.354m) = 484 Hz
Does this look OK?
