disk until the light transmitted through the disks is at a mini-

mum. Put a small piece of polarizer material between the

two Polarizer Disks, and adjust its angle until the light trans-

mitted through the three polarizers is a maximum. Note the

angle of the piece of polarizer material.

Set up the Polarizer Disks so that they are cross-polarized as

before. Put a pair of sunglasses between the two polarizers

and rotate the sunglasses from horizontal to vertical. Note

any change in appearance of the light transmitted through the

two polarizers and the pair of sunglasses.

Observe a light source through both Polarizer Disks. Set one

Polarizer Disk at zero degrees and the second at 90 degrees.

Next, put a clear piece of plastic between the two Polarizer

Disks. Note the appearance of the clear plastic object. Flex

or twist the plastic object and note any change in appearance

of the object.

Polarizer Demonstrator Accessory

The PASCO Model OS-8172 Polarizer Demonstrator Acces-

sory works with the Polarizer Demonstrator to show the

property of optical activity - the ability to rotate plane-polar-

ized light. In 1874, the Dutch chemist Jacobus Henricus

van’t Huff proposed that the tetrahedral structure of the car-

bon atoms in optically active materials was responsible for

the behavior.

The OS-8172 includes a bottle support, two rectangular sam-

ple bottles with lids, a diffuser screen, and thumbscrews for

attaching the bottle support and diffuser screen to the Polar-

izer Demonstrator stands.
