Argument for relationship between scale length and frequency

Click For Summary
SUMMARY

The discussion centers on the relationship between scale length and frequency in wave mechanics, specifically in the context of string vibrations. It is established that a longer scale length correlates with a longer wavelength, leading to a lower frequency as described by the formula f = v/(λ). The wave equation provided, ∂²y/∂x² = (1/v²)·∂²y/∂t², illustrates how wave speed (v) is influenced by the tension and linear density of the string, reinforcing the connection between scale length and frequency.

Homework Statement


Give an argument for there being a connection between scale length and frequency

Homework Equations



scale length = (wave length) / (Length)

The Attempt at a Solution



So from only my physical intuition I'm coming up with the longer the scale length the longer the wave length and thus by f = v/(lambda) the smaller the frequency. But is there a more physical interpretation of this?

It comes from the wave eq. (in one dimension, for instance):

\partial2y/\partialx2=1/v2·\partial2y/\partialt2

as v is derivated from the tension on the string and its linear density.
