A wire of length 1.20m is fixed at one end and stretched. A transverse wave moves with a speed of 300 ms along the wire and is reflected at the fixed end. In the stationary wave set up, two successive nodes are seperated by a distance of 0.40m. What is the frequency for this mode of vibration?

Best ResponseYou've already chosen the best response.1\[c=f lambda\] and they tell you that the nodes are a distance of the nodes are 0.40m apart and the distance between nodes is half a wavelength so lambda = 0.80m so you get \[c/0.80=f\]

Best ResponseYou've already chosen the best response.0\[\frac{\lambda}{2} \times 1 = 1.20\] \[v = f_{0} \times \lambda\]

Best ResponseYou've already chosen the best response.1In this case it is not c but it is v. I used the formula for light in a vacuum
