Calculating Wave Velocity with Frequency and Amplitude

Click For Summary

Homework Help Overview

The discussion revolves around calculating wave velocity using frequency and amplitude, specifically for a transverse wave. Participants are exploring the relationship between wave properties without explicit information on wavelength.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants question how to calculate wave velocity without wavelength, discussing the wave equation and the role of amplitude. There are inquiries about the relationship between wavelength, period, and frequency.

Discussion Status

The discussion is ongoing, with participants providing insights and clarifications regarding the information needed to solve the problem. Some guidance has been offered about the definitions of wavelength and period, but no consensus has been reached on how to proceed with the calculations.

Contextual Notes

There is a lack of information regarding the specific type of wave and its conditions, such as whether the string is in resonance or its mass density. This missing context is noted as a constraint in addressing the problem.

Anyone know how to calculate the wave velocity if you know the frecuency, but not the wavelength? We were also given the amplitude.

Wave velocity of what? The wave equation is [tex]v = f \lambda[/tex], so unless you have other information you won't be able to find the speed. (Amplitude won't help.) What's the exact problem?
 
A transverse wave, with amplitude 13 cm, and frecuency of 5.00 Hz...No wavelength mentioned.
a) Find the velocity of the wave.
b)Find the total distance traveled by a particle on the wave after 3 seconds.

How come the wavelength isn't the period of the function, or the reciporacal of the frecuency?

Of what? A wave on a stretched string?
a) Find the velocity of the wave.
b)Find the total distance traveled by a particle on the wave after 3 seconds.
I don't see enough info to answer part a, but b seems doable.

How come the wavelength isn't the period of the function, or the reciporacal of the frecuency?
Wavelength is a length, period is a time. How can they be the same? (They are related by wave speed, given by the wave equation.) Period is the reciprical of frequency.
 
Be more careful in your reading of the problem ...
they're probably trying to ask about (or tell you about)
the maximum speed or acceleration of a PIECE of the STRING.
Do they tell you that the string is in resonance? mass density?
