Intro to Polarization Filters! or...why are those sunglasses so expensive? | Doc Physics

We figure out why light waves that are shaking a certain direction can make it through polarization filters while others can't. We also hint at the Law of Malus and more beautiful Polaroid filter combinations.

FINALLY SOME ONE WHO CAN ACTUALLY EXPLAIN PHYSICS WITHOUT MAKING IT BORING! Physics is probably the most interesting subject - yet every where I look people have managed to make it such an unfriendly topic! Thank you so much :D

Well done brother.I am Physics student and i had a project in polarization weeks ago and you refreshed my knowledge there.

Hands down the best demonstration I've seen on this topic. Thank you :)

I'm dodgy because I'm not an expert. You'll want an engineer for that question, since I believe it is a standard analysis technique for stress and strain in materials. I'd love to hear what you learn! Thanks for watching!

Those experiments were AMAZING!!! Funny how we could see through!! 

[giorgixyz]

your excitement is so passionate I love it

[DocSchuster]

Those are great ideas. I'll put them on my short list! Thanks for your interest.

I really love the way you explained it.You sir are a great teacher.

[msSnilloc]

This is hilarious and so helpful. Thanks a million :D

Doc you are the boss !!! All teachers/lecturers should be like you to make this world a better place. With lecturers like you around everybody could easily become a quantum physicist. In short, we desperately need to clone you !!!

[apotter]

Thank you. I have been reading and watching many videos on this, and finally YOURS explains it! :)

[dipanshu]

Doc you r awsm buddy. Best physics instructor

[shafiruki]

You are so quick, very nice doc master physics

[cameronroffey]

Honestly you made this so much easier to understand! Thanks so much!

[zyadbama]

Absolutely amazing!
Keep up the good work! 

[DocSchuster]

Mariam - I am sorry to confuse you!  I elected to only draw and discuss the electric field.  But you are correct.  The magnetic field is destroyed simultaneously when the electric field is.  The light as a whole is absorbed.

I got a crystal clear idea of polarization of light. Thank you so much ^_^

Omg. that was the first time I ever said "That was AWESOME" and smiled while learning smtg about physics. you sir, gave me all the motivation I need to do well on my exams. Thank you.

[Blinkc]

just an enormous thank you!! really helpful!

doc you are so close to answering my lab question for me
