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.

Amplitude 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;

U is the average power of the wave
T is the tension in the wire
ω angular frequency of the wave
A is amplitude of the wave
v is the speed of the wave
f is frequency of the wave

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.
