Description
Demonstrate the relationship between length, frequency, and resonance. Vibrate these metal strips of different lengths with a Wave Driver (WA-9855) and a signal generator. As you sweep through a range of frequencies, each metal strip will resonate in its turn according to its length. The six steel strips have lengths varying from 7 cm to 13 cm.
Product Summary
This newly redesigned Wave Driver offers improvements in driving force and amplitude as well as a built-in string guide so tiny parts don’t get lost. It is ideal for vibrating waves in a string, driving Chladni plates to show the vibration modes, or to demonstrate resonance vibrations.
Use a function generator (sold separately) to power this Wave Driver.
Features
- New improved design
- Greater amplitude
- Stronger magnet for stronger force
- Sturdy construction
Built-in Features
- 0.5-inch (1.3 cm) rod clamp
- String slot in driver post
- Hole through driver post for tying string
- Fuse protection
- Shielded banana jacks
- Rubber base
Applications
- Standing waves in a string
- Chladni plate resonance modes
- Demonstration of resonance using vibrating metal strips
- Demonstration of standing longitudinal waves in a spring
How It Works
A coil inside a cylindrical magnet is driven by a sinusoidal signal which comes from the external function generator that is connected to the Wave Driver’s banana jacks. The coil is attached to a diaphragm that the actuator rod is connected to.
