PHY 1611L Lecture : lab 11- Standing Waves in a String

STANDING WAVES ON A STRING-(experiment)
1)Would the standing wave patterns be altered if our strings weredispersive?

2)What would you expect the standing wave pattern to look like ifthis experiment used a composite string made of half thick stringand half thin string tied end to end? Draw a picture showing thepattern.

Oscillation of a 170 Hz tuning fork sets up standing waves in a string clamped at both ends. The wave speed for the string is 520 m/s. The standing wave has four loops and an amplitude of 4.7 mm. What is the length of the string
