Tweety Bird hops up and down at a frequency of 0.4 Hz on a power line at the midpoint between the poles, which are separated by 18 m. Assuming Tweety is exciting the fundamental standing wave, find the speed of transverse waves on the power line. (Hint: What is the wavelength for this standing wave?) need to know how to get m/s?

If the wavelength is λ, you know that 18m = λ/2.

Now, speed (m/s) = 36m*.4/s = 14.4m/s
