Answer to Question #88208 in Quantum Mechanics for pooja

Question

describe an simple experiment to determine whether sunglasses in the store are polarizing

Answer 1

all you have to do is hold two identical pairs in such a way that you can see straight through them both. As you turn one pair slowly to 90 degrees, your vision through the second lens should get visibly darker. If the lenses aren't actually polarized, you shouldn't notice a change.
