What is the relationship between Wavelength(λ) and Amplitude?

Click For Summary

Homework Help Overview

The discussion revolves around the relationship between wavelength (λ) and amplitude in the context of wave properties, specifically in relation to sound waves and their characteristics.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the implications of changing frequency and wavelength, questioning how these relate to amplitude. There is a focus on understanding whether amplitude has any direct relationship with wavelength.

Discussion Status

The conversation is ongoing, with participants examining the definitions and relationships between the concepts of wavelength, amplitude, and frequency. Some guidance has been offered regarding the lack of a direct relationship between wavelength and amplitude based on the provided equation.

Contextual Notes

Participants are navigating assumptions about wave properties and the definitions of terms like amplitude and wavelength. There is an emphasis on understanding the implications of the equation V = fλ in relation to amplitude.

What is the relationship between Wavelength(λ) and Amplitude?

Homework Equations


V = fλ

The Attempt at a Solution


Well, i know an increase in frequency will cause a higher pitch, but what happens when the wavelengths increase of decrease?

Hi bob-e, welcome to PF.

Think of amplitude as volume. Does pitch depend on volume?
 
thanks!

well, I don't think volume depends on pitch but yeah you are right, amplitude does
but what is the relationship between wavelengths and amplitude? and why? that's the part I do not understand
 
Look at the expression you wrote down, V = fλ. It says that if V is constant, changing the wavelength changes the frequency. There is no mention of amplitude anywhere. Do you have an expression that relates wavelength and amplitude? If "no", then the two are not related.
