What is the period of a standing transverse wave on a flexible string?

AI Thread Summary
The discussion revolves around calculating the period of a standing transverse wave on a flexible string, which is 1.34 m long, under a tension of 6 N and with a mass of 12.22 g. Participants clarify that the string's length corresponds to one and a half wavelengths of the wave. The process involves first determining the wave speed using the string's tension and mass, which then aids in finding the wavelength. Confusion arises regarding the relationship between the string length and the wavelengths, but participants work through the problem collaboratively. Ultimately, the focus is on using the derived values to calculate the period of oscillation.

The diagram represents a snapshot of a standing transverse wave on a flexible string taken when the displacement is at a maximum. The string is 1.34 m long with tension 6 N. The total mass of the string is 12.22 g. Find the period of the oscillation.

The diagram is unlabeled. it just shows one and a half wavelengths.


a loop up, a loop down, another loop up. is what it looks like.

i don't know if that makes sense.. it's pretty simple i just don't know how else to show you the diagram.

I think I understand what the diagram looks like. What I don't see is any question!

Find the period of oscillation.
 
Start by finding the speed of the wave. Hint: That speed depends on the tension, mass, and length of the string.
 
I found that, but what can i do next?

I have the length of the string, but i can't seem to find a way to find the wavelength, or the length of 1 1/2 wave lengths.

According to your description, doesn't the length of the string equal 1 1/2 wavelengths?

Maybe i should try that again, i just got confused on what length meant.
 
Got it! thanks! hadn't tried that with my new velocity.

Much appreciated.
