Basic Idea:

• Use wave theory to determine the physical characteristics of the vibrating string.

	What:	How Many:	Where:
	Pasco String Vibrator & string	1	non-Majors storeroom, shelf F2
	Variac (Blue preferred)	1	Blue: non-Majors storeroom, shelf L3 Black: Majors storeroom, shelf E3
	Large bench clamp	1	non-Majors storeroom, shelf C4
	Small pulley clamp	1	non-Majors storeroom, shelf C4
	Pulley on rod	1	non-Majors storeroom, shelf E4
	Masses: 50, 100, & 200g	2 – 200g 1 – 100g 1 – 50 g	non-Majors storeroom, shelf D3
	50g mass hangar	1	non-Majors storeroom, shelf D3
	Meterstick	1	non-Majors storeroom, shelf AA2
	Meterstick calipers	2	non-Majors storeroom, shelf AA3
Place the following on the Instructors table:
	Strobe light	1 (shared for demo only)	non-Majors storeroom, glass cabinets

Computers Needed?

• Yes (see KaleidaGraph notes below).

• Lab setup (See this page for detailed photos):

  

  ---

• String setup (Note #1: Use a small pulley clamp to mount the pully! See detailed photos page!)

  
  Note #2: Make sure mass hangar doesn't interfere with pulley post.

• KaleidaGraph note: KaleidaGraph needs a General fit called "Square Root" (it should already have been added for the Simple Pendulum experiment):

  a*x^0.5; a=1
