Homework Statement:
A microwave generator can produce microwaves at any frequency between 10.0 GHz and 20.0 GHz. The microwaves are aimed, through a small hole, into a "microwave cavity" that consists of a 10.0cm -long cylinder with reflective ends.

A. Which frequencies between 10 GHz and 20 GHz will create standing waves in the microwave cavity?
Relevant Equations:
L=c/f
I tried to fix this physics problem. But i think I’m using the wrong steps.

Yes I just realized that I was using the wrong method for standing waves cavities, the question was asking about close - close between cylinder microwave cavities... thanks for the hint
