Product Description

A Proven Performer for Basic Wave Motion Studies

Ideal for investigating the vibration modes of stretched strings and for Melde’s experiment, the sting vibrator provides a powerful, constant frequency, oscillating source for up to three monofilament string simultaneously.

Ease of use has made this device a popular choice:

  • Clamps directly to the bench using a C-clamp
  • Strings attach directly to the spring
  • Plugs directly into a wall outlet – operates immediately

Improved design now makes our unit even better:

  • Clamping block located away from the active spring area
  • Improved spring clamping system needs no adjustment
  • Robust, enclosed case for electrical safety

How It Works

A tuned spring steel strip is set in resonant vibration by an a.c. powered coil. Monofilament string attached to the end of the spring is tensioned by slotted wieghts anging ovewr a pulley at the end of the bench. By adjusting the tension, the string can be tuned to observe different resonance modes, and the velocity of the waves on the string can then be found by measuring the distance between nodes for the various modes. Further experiments on string waves can be performed by varying the string’s vibration length and by using strings of different masses.

Includes operation and experiment manual.
