Exploration #3

Exploration #3 Now make a stack of the two polarizers and look through them. Flip one over. What do you see now? Flip the other. Hold one still and rotate the other like you did in exploration #1. What do you see...

Exploration #2

Exploration #2 Now make a stack of the two polarizers and look through them. Flip one over. What do you see now? Flip the other. Hold one still and rotate the other like you did in exploration #1. What do you see...

Exploration #1

Exploration #1 Hold one sheet of polarizer (the dark greyish one) in front of a computer screen, TV, smartphone or any other “flat screen.” (The screen should be turned on). Rotate the polarizer slowly. What do you see? Try this with several devices! Does it matter...
