M-W3   :   Pulse on String

UNIT: Transverse waves
PURPOSE: Compare waves speed for two different strings
EQUIPMENT:
1. Two strings of different mass density
2. Clamp to secure one end of strings
SUGGESTIONS: Set the strings in parallel and ask students to predict on which will a pulse travel faster if 
1. Strings loose
2. Strings taut with the same tension
