- Equipment List
- Introduction
- Equipment Setup to Determine the Effect of Tension on Wave Speed
- 1. Tie one end of the elastic cord to a table clamp or ring stand.
- 2. Place the wave driver on a tabletop and pass the elastic cord through the grove on the post.
- 3. Tie the other end to a mass and hang the cord over a pulley about 3 meters away.
- 4. Plug the power supply in and begin generating waves in the cord.
- 5. Using your hand raise the mass until it is just over the pulley; count the number of standing ...
- 6. Calculate the wavelength with the following equation:
- 7. Record both the frequency and wavelength in a data table.
- 8. Increase the tension by pulling down on the mass until a new standing wave pattern is formed.
- 9. Repeat steps 6-7 for the new tension.
- 10. Increase the tension four more times, each time recording the frequency and wavelength in the...
- 11. Use your data and the general wave equation (v = ƒl) to determine the velocity for each tension.
- 12. What relationship exists between wave speed and tension?
- Equipment Setup to Determine Resonance Frequency
- 1. Tie one end of the elastic cord to a table clamp or ring stand
- 2. Place the wave driver on a tabletop and pass the elastic cord through the grove on the post.
- 3. Tie the other end to a mass and hang the cord over a pulley or table edge.
- 4. Set the frequency to 1 Hz and increase slowly until the fundamental (1/2 wave) frequency is de...
- 5. Increase the frequency slowly until the 1st harmonic is reached (1 wave). Record the frequency...
- 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 = ƒl) and your data, calculate the velocity of the waves in...
- 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 fr...
