Consider the standing wave pattern with 4 antinodes. This standing wave is on a wire of linear mass density 3g/m and length 2m. It is being driven by a magnetic vibrator on the end of the wire, wiggling the wire up and down at 120 Hz, find tension. The answer must be in Newton. The tension is now slowly increased, causing the standing wave pattern shown to disappear. At certain higher tension the next standing wave pattern appears. Tell how...

A continuous traveling wave with amplitude A is incident on a boundary.The continuous reflection, with a smaller amplitude B, travels back through the incoming wave.The resulting interference pattern is displayed in thr figure. The standing wave ratio is defined to be A+B SWR=2 A-B The reflection coefficient Ris the ratio of the power of the reflected wave to the power of the incoming wave and is thus proportional to the ratio (B/A)2. What is the SWR for (a) total reflection...

A standing wave pattern is created on a string with mass density u- 3x 10 kg/m. A wave generator with frequency f- 65 Hz is attached to one end of the string and the other end goes over a pulley and is connected to a mass (ignore the weight of the string between the pulley and mass). The distance between the generator and pulley is L- 0.74 m. Initially the 3rd harmonic wave pattern is formed. What is the wavelength...
