Experiment 4: Standing Waves

Objective:
To make different nodes and oberve the difference for standing waves on a string.


Equipment:

 

 

 

Pasco variable frequency wave driver
String
Pasco student function generator
Weight set (grams)
Pendulim clamp
Pulley
Digital Multimeter
Meter stick

Procedure: We took measurements mass, and length of the string. We then took measurements of harmonics. We got different levels of harmonics from changing the frequency of the function generator. We did this in two different cases. When doing the second case it is one-fourth the original tension.

Data:
