The amplitude of the wave is determined from the tension in the wire, speed of the wave, frequency of the wave and average power of the wave.
The amplitude of the wave travelling at the given frequency and power is calculated as follows;
U = (¹/₂)(T/v²)(ω²)(A²)(v)
U = (¹/₂)(T/v)(ω²)(A²)
U = (¹/₂)(T/v)(2πf)²(A²)
where;
Thus, the amplitude of the wave is determined from the tension in the wire, speed of the wave, frequency of the wave and average power of the wave.
