# Amplitude-frequency relationship

Hello.
I was doing a chemistry test, one question was asking to state the relationship between the amplitude and frequency of a wave.
I wrote that they had no relationship, as amplitude can go higher with frequency staying the same. Was I right?

This depends entirely on the context. If the "generator" of that wave has a constant power source, then yes, there is a dependence between frequency and amplitude. If the context is a simply wave problem, then maybe they're simply testing you on $v=f\lambda$. Then in that case, there isn't.

Actually the test was mainly on photons and formulas just like $$\upsilon=\lambda\nu$$. What you mean with constant power source?

Meaningless question I would have thought without some context.
