Basic Idea:

• Examine the optical properties of lenses (using Pasco optical benches).

Number of setups:

• 6

	What:	How Many:	Where:
	Pasco Optical bench (see setup diagram)	1	Majors storeroom, shelf P4
Note: All of the optical bench accessories are located in a single box (one per track), located on the N shelves
	Screen	1	Majors storeroom, shelf N
	Light source	1	Majors storeroom, shelf N
	Lenses: 3 converging: +150 mm, +200 mm, +250 mm 1 diverging: –150 mm	1 each	Majors storeroom, shelf N

Computers Needed?

• No.

• Lab setup (See this page for photo details; Make sure that the light source is closest to the window, as shown below. Also note how the optical benchs are staggered; make sure that the ruler always faces the outer edge of the lab bench, again as shown):
