The motion of bird on a 200 m long electrical transmission wire suspend between two poles can be described a Simple harmonic oscillation. The bird is located 50 m away from one of the poles and its setting a transverse standing wave at the fourth harmonic. Assume the mass of the bird to be negligible relative to the mass of the wire. a. Sketch this situation and sketch the standing wave. b. Use your sketch to justify If the bird is at a node or antinode? c. Use your sketch to find the wavelength of this standing wave.?
