# Method to produce and measure velocity of a standing wave

## Homework Statement

I'm in a Year 10 physics class. We have been asked, for homework, to design an experiment to measure the velocity of a standing wave. No other information has been given other than that.

I reproduce the exact instructions we were given, since the guidelines suggest I should:

The velocity of Standing Waves?????

You are to find a way to measure the velocity of a standing wave that you can make. You must change that velocity somehow, and find a relationship with another variable.

Good luck!

## Homework Equations

I did some research into waves and standing waves and I found that to find the velocity of a wave I use the formula $v = f\lambda$. I'm not quite sure how this formula applies to a standing wave, since a standing wave doesn't really move... was I supposed to measure the speed of the individual waves that make up the standing wave? Or the speed at which the standing wave vibrates at the antinodes?

## The Attempt at a Solution

Initial research into types of standing waves suggests I could use a string for the medium. I'm not sure what I could use to start the vibrations in the string though. Any help would be greatly appreciated.
