One end of a long brass wire is moved up and down with simple harmonic motion (SHM), with amplitude 0.08 m and a frequency of 45 cycles per second. The wave travels along the wire at a speed of 80 m/sec.
Write the wave equation in terms of k and angular frequency w.
The solution writes a wave equation given the constants amplitude, frequency and speed. With explanations and formulas, the problem is solved.
