1. The problem statement, all variables and given/known data
What is the relationship between Wavelength(λ) and Amplitude?

2. Relevant equations
V = fλ

3. 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.
