4.2 Travelling waves

Experiments

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

Speed of Sound

Experiment #33 from Physics with Vernier

  • Measure how long it takes sound to travel down and back in a long tube.
  • Determine the speed of sound.
  • Compare the speed of sound in air to the accepted value.

Slinky Wave Speeds

Experiment #19 from Physics with Video Analysis

In this activity, you will

  • Study movies that show transverse and longitudinal disturbances moving along a stretched Slinky lying on a very slick (low friction) floor.
  • Think about the process by which the disturbances propagate along the Slinky, measure the wave speeds, and consider what properties of the Slinky will affect the speed of the waves.
