3B25.67 - Culvert Whistlers

Code Number:
Demo Title:
Culvert Whistlers
Culvert Whistlers
Area of Study:
Space Phone or Slinky.

See also 3B25.67 in Astronomy and 8A70.70 in Astronomy.

The "Space Phone" allows you to hear whistlers as the speed of sound transmission through the spring is wavelength dependant.  A long Slinky can also be used for this demonstration.
