5. Increase the frequency slowly until the 1st harmonic is reached

(1 wave). Record the frequency and wavelength in a data table.

6. Repeat step 5 until four full standing waves have been produced.

7. What pattern do you notice for the resonance frequencies?

8. What relationship exists between frequency and wavelength?

9. Using the general wave equation (v = ƒ

λ) and your data, calculate

the velocity of the waves in the string.

10. What pattern do you notice about the wave velocity at each

resonance frequency?

11. Starting with the general wave equation, create an expression

which predicts the resonance frequencies for each standing wave
pattern in a string.
