Discuss the physics behind the demonstration, explaining some of the various steps of the demonstration when appropriate. Standing waves form in the organ pipes when air is pushed through them.

Red and White Gas Carts

Located beneath lecture bench in rooms 2103 and 2241

Important Setup Notes:

  • If you'd like to sound the organ pipes, a supply of compressed air is required (usually from the red and white gas carts).

Setup and Procedure:

  1. Arrange the set of organ pipes (forming a full scale) in order by tone.
  2. If desiring to sound the pipes, place the base on the table and connect to the compressed air supply.
  3. Make sure the valves in the base are open: pull out wooden knob located beneath each organ pipe.
  4. Open the air supply valve.
  5. Adjust volume by adjusting how open the valves in the base are.

Cautions, Warnings, or Safety Concerns:

  • If using the red and white gas carts, make sure you are using compressed air and NOT METHANE gas which is highly flammable.

Discussion:

Standing waves form in the organ pipes when air is pushed through them. The fundamental frequency of each pipe (the note that plays) is determined by the length of the pipe and whether or not the end of the pipe is open or closed.
