Equipment List:

1. LabPro interface with:     
   • Vernier Light Sensor (ANALOG CH1) (D7.1)
2. Vernier Optics/Dynamics Track (A7.2) 
3. Vernier Light Source (D7.4) with 10cm lens in lens holder for focusing beam (D7.5)
4. Two calibrated polarizers (D7.2) in Vernier lens holders (D7.1)
5. Four Vernier component carriers (D7.4) and one Vernier screen holder (D7.2) for optical bench
6. Holder for light sensor (D7.2)
7. One loose polarizer in frame (D7.2)
8. Brewster's law accessory with rotating arm and sem-circle lens (C2.2)

1. Test that all light sources work.
2. Check the alignment of the optical bench so that you read a decent amount of "lux" (between 400 and 700) when the light beam is focused right onto the light sensor.
3. Make sure the 0 of the brewster's angle accessory is lined up with the center of the track. The initial setup should have the rotating arm at 90 degrees, so if it doesn't look perpendicular to the track you know it's not correct.
4. No need to be too over precise with the alignment since everything will get moved around quite a bit anyway. They will have to adjust for the height of the brewster's angle accessory themselves.
5. Open "Polarization.cmbl" in the Lab22 folder in class notes and test the light sensors.
