Homework Equations
P=½ √μF ω2 A2
The Attempt at a Solution
How is the equation related to the wavelength?
Thanks
Your relevant equation has frequency in it. What connects that with wavelength?ChloeYip said:How is the equation related to the wavelength
It's your equation. If you say F is tension you must be right. (What's μ?)ChloeYip said:Where is frequency in the equation?
the F in the equation isn't meaning force (i.e. tension)?
Since wave velocity is √(tension/linear density), the two equations are the same.ChloeYip said:well, i think w is directly proportional to frequency from this web, leading the answer b, right?
frankly, i just copy the equation from my textbook "university physics" of Young & Freedman
every symbol means the same to the website other than F is missing in the website.
does it mean anything for the difference?
thanks
what i mean is w = 2 pi fChloeYip said:w is directly proportional to frequency
thanks for telling me this new thing :)haruspex said:wave velocity is √(tension/linear density)

The power of a wave on a string refers to the rate at which energy is transferred through the string as a result of the wave's motion. It is dependent on the amplitude and frequency of the wave.
The power of a wave on a string is directly proportional to the square of the amplitude of the wave. This means that as the amplitude increases, the power also increases.
Yes, the frequency of the wave also has an impact on its power. Higher frequency waves have a greater power because they transfer energy at a faster rate than lower frequency waves.
Yes, the power of a wave on a string can be changed by altering its amplitude or frequency. For example, increasing the amplitude of a wave will increase its power, while decreasing the frequency will decrease its power.
The power of a wave on a string does not directly affect its speed. However, a higher power wave may have a larger amplitude and therefore travel faster than a lower power wave with a smaller amplitude.
