Pasco - Model WA-7428 - Sonometer - Manual

The Sonometer is an apparatus used for exploring the wave properties of vibrating strings. It includes two mounts to install strings of different linear densities. String length is varied by changing the position of a sliding bridge under the string. String tension is varied by hanging masses from the lever attached to the end of the string. To vibrate the strings, pluck them with a pick or use resonance by vibrating a tuning fork. Use a sound sensor with SPARKvue or PASCO Capstone to measure the frequency of vibration.
