Solving Resonance: Ideas to Get Started

[LTU83]

I don't want the answer to this problem just an idea of how to get started. I don't understand what I am looking for. Thanks.

Homework Statement

A 143-cm-long pipe is stopped at one end. Near the open end, there is a loudspeaker that is driven by an audio oscillator whose frequency can be varied from 10.0 to 4700 Hz. (Take the speed of sound to be 343 m/s.)

Homework Equations

freq= v / λ (just guessing)

The Attempt at a Solution

I don't understand what you are looking for either. There is no question attached to the statement of the situation, but f = v/λ is correct regardless.

I presume you want to find the resonant frequency of the pipe. Let's narrow it down a bit. Will it be when the length of the pipe is equal to 1/4 wavelength, 1/2 wavelength or 1 wavelength of the frequency?
