The power of a wave measures the amount of energy the wave transmits in per unit time
The correct option that could increase the power of a wave in a spring is option D.
D. All of the above
The reason the selected option is correct is given as follows;
The power of a wave in a string is given by the following equation;
- [tex]Wave \ power = \dfrac{1}{2} \cdot \mu \cdot \omega^2 \cdot A^2 \cdot v[/tex]
Where;
μ = The string's mass per unit length
ω = The wave's angular frequency
A = The wave amplitude
v = The velocity of propagation of the wave
[tex]v = \sqrt{\dfrac{T}{\mu} }[/tex]
T = Tension in the string
Increasing the power of the wave in a string, can be done by either;
- Increasing the wave amplitude
- Increasing the velocity of the wave by increasing the frequency (v = f·λ)
- The velocity of the wave is increased when the tension is increased, therefore, increasing the tension, increases the power of the wave in a string
Therefore, all the options are correct
