4.5 Standing waves

Experiments

Here are experiments our science specialists have selected to support the IB* topic.

Standing Waves on a String

Experiment #3 from Advanced Physics with Vernier — Beyond Mechanics

In this experiment, you will

  • Adjust the frequency of the driver so that the string vibrates in the fundamental mode.
  • Set up other standing wave patterns on the string.
  • Relate the frequency of the various harmonics to that of the fundamental mode of vibration.
  • Describe the terms amplitude, frequency, wavelength, node, and antinode as they relate to vibrating strings.
  • Determine the velocity of waves in the string.
  • Relate wave velocity to the tension of the string and its linear density.

Standing Waves in a Column of Air

Experiment #4 from Advanced Physics with Vernier — Beyond Mechanics

In this experiment, you will

  • Set up standing wave patterns in a column of air in open-end and closed-end tubes.
  • Determine the relationship between tube length and wavelength for these standing waves.
  • Use transverse wave patterns to describe the nodes and antinodes that occur in a column of air in open-end and closed-end tubes.
  • Determine the speed of sound in air.
