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

Click For Summary

Homework Help Overview

The discussion revolves around determining the period of oscillation for a standing transverse wave on a flexible string, given its length, tension, and mass. The original poster describes a diagram depicting the wave's displacement at maximum, noting the string's physical properties.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the relationship between the string's length and the wavelengths of the standing wave, questioning how to derive the wavelength from the given length. There are attempts to clarify the setup and the implications of the diagram.

Discussion Status

Some participants have provided hints regarding the wave speed and its dependence on the string's properties. The conversation reflects a mix of understanding and confusion about the relationship between the string length and the wavelengths, with no explicit consensus reached yet.

Contextual Notes

There is a lack of clarity regarding the interpretation of the string's length in relation to the number of wavelengths, which some participants are actively questioning. The original poster's diagram is also noted to be unlabeled, which may contribute to the confusion.

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.
