6.1 Nature of Light and the Photoelectric Effect | General Chemistry

Chad you are seriously a gem of a human being. I am so grateful for you. I aced my first chemistry exam back after studying finance for 4 years. God bless you.

[@ChadsPrep]

Thanks for saying so - Happy Studying!

[@tylerstephens6901]

Love the camera, love the lesson, love everything. Currently doing gen chem in college and your videos are saving my grade!!!!

[@ChadsPrep]

Glad to hear it, Tyler!

Sir you were saying the photon has to have eV at least 2ev if the w.function is 2ev. But according to the the equation if photon ev is 2ev then KE will be 0....then the electron wont move....then we have to remove "at least" word. I just want to confirm if i am right..awesome videos. I began chemistry at undergraduate and you just made me love it.

Amazing video thank you very much.

[@ChadsPrep]

You are welcome!

[@dogaveyasam93]

Thanks for making science more fun! Learnt a lot!

[@ChadsPrep]

You're welcome - glad to hear it!

Camera image looks great . It reveals more of a shadow behind you, but the white board is crisp

[@ChadsPrep]

It is a great camera, not perfect, but waaaayyyy better than my previous one!

[@bridgette9148]

Great camera and great explanations❤!

[@ChadsPrep]

Excellent and Thanks!

[@laurasteiert7749]

Camera looks great, very clear!

[@ChadsPrep]

Thanks for the feedback, Laura!

[@chemistryrussell]

Great shirt and great lesson!!!

[@ChadsPrep]

Thank you twice!

And then it bothers me that during the interaction of the incident photon with the electron in the metal, the conservation of momentum and energy is not respected. To obtain the energy balance, the extraction work Wex is added to the equation. Something that is a subsequent effect of the interaction of the photon with the electron in the metal. The mechanism of the photoelectric effect is based on an electric impulse of induction that occurs during the rapid damping of the standing wave, of high amplitude, constituted by the constructive interference of the wave titles from the component of the wave packet of the incident photon in the metal. The high-amplitude wave of the photon refracted in the metal appears after the contraction of the photon both longitudinally and transversally and its refraction at 360 degrees, in the atomic environment, of high energy density. The stationary wave, of high amplitude, propagates on the circle of the Rfm metal photon radius, with a speed of C/137 (m/s) and behaves like an elementary electric charge, which produces a current in the coil. When the high-amplitude standing wave breaks, the electric impulse appears, through electromagnetic induction, which accelerates the electron in the immediate vicinity.

im struggling so hard.. my chemistry teacher uses angstrom, cm, Kcal, ev, etc but no chemistry video I find use those and i dont really understand any lesson 🥲

[@ChadsPrep]

Hey Chutie :) I am sorry you are struggling with those units - as long as you can understand the concepts then you could just substitute in the units you use in the course as those will be given to you. Do you have a good conversion chart?

[@TheZmoliver]

This is the problem with cranking out an entire chapter's worth of lessons in one day... Respectfully, Chad, you look and sound like you're just trying to get them over with as fast as possible without any regard for explanation of concepts. I do subscribe to the master course and I think it's great. So I mean this in a good way when I say, I've just come to expect better.

new camera is awesome!!!!!

[@ChadsPrep]

Glad you think so, Shegufta - it is a BIG difference. Thanks for noticing!

[@universalduggal1708]

Do you go over the Blackbody radiation?

[@user-jy7mp2uw6i]

cool camera!

[@ChadsPrep]

Thanks!

rad.shirt 🙂

[@ChadsPrep]

Thanks!

[@norman9052]

camera is great

[@ChadsPrep]

Thank you.

[@SQ.c5]

Yey

[@ChadsPrep]

Happy Studying!

[@languagetellsus]

And i just understood Quantum mechanics...it means i dont understand it🤣

[@ChadsPrep]

Indeed!
