Question

What must the amplitude of a traveling wave of frequency 72.0 hz be in order for the average power carried by the wave to be 0.363 w ? express your answer with the appropriate units.

Answer 1

The tension in the wire, the wave's speed, its frequency, and its average power are used to calculate the wave's amplitude.

To find the answer, we have to know about the simple harmonic motion.

How to find the amplitude of a traveling wave?

• We have the expression for average power carried by the wave as,

                                 P = (¹/₂)(T/v²)(ω²)(A²)(v)

                                 P = (¹/₂)(T/v)(ω²)(A²)

                                 P = (¹/₂)(T/v)(2πf)²(A²)

where; U is the average power of the wave, T is the tension e wire, ω angular frequency of the wave, A is amplitude of the wave, v is the speed of the wave and f is frequency of the wave.

Thus, the tension in the wire, the wave's speed, its frequency, and its average power are used to calculate the wave's amplitude.
