3. Wave-Particle Duality of Light

MIT 5.111 Principles of Chemical Science, Fall 2014
Instructor: Catherine Drennan

The idea that light is both a wave and a particle is introduced. The properties of waves are described and the applications of diffraction are presented.

Omg. These are good. You don’t just throw equations, but explain where they come from and why they make sense in a simple manner.

I'm not from the us but you can't imagine how helpful was that for me, to see the greatest educational institution offers the help hand to all students from all countries and for free. thank you MIT on behalf of all the students

15:50 Roy G Biv; 27:48 duality ; PE effect; 30:20 Graph freq vs KE; 31:18 Int vs KE; 33:20 h Planck constant

The more I see these videos, the more I realize that what I receive at school isn't really an education...

These are pretty great. I finished my biochem degree, coming back and watching these to make sure any gaps I might have in chemistry are filled. After seeing a lot of comments talking about their terrible university lecturers, I'm much more grateful to mine. I didn't go to any Ivy, but I certainly did learn and loved my lectures.

The creativity in play here is stunning!

This makes a lot of sense to me.
I got a clear picture when she explained the graph of KE vs Frequency

This is an excellent lecture. Thanks, Prof. Drennan. You made me understand the wave-particle duality of light so easily.

[donboscongwina]

Thank You Dr. Drenna. Your lectures help me understand General Chemistry better.

This lectures are really good!! Thank you!!!

[shb]

Thanks a ton Prof. Drennan & MIT, these lectures are really helpful for my high school chemistry back here in India, and yes I promise 23:04

[helicalactual]

that was so YOUR THE BEST PROF DOC DRENNAN!!

[Adharsh]

While watching the video I have a same feeling that of sitting in MIT.

[agabriela]

Wow, these are phenomenal. I wish I had these videos when I was in highschool

[natashashvetz]

Thank you for revealing the truth. E = hf shenanigan is not the "internal" energy of electron. From KE = hf - hf0 we see that speed of the ejected electron depends on the frequency of light.

[Spacexioms]

Even in 1.5 speed, it’s fairly easy to follow this teacher

[fantoom]

I love these lectures, and I love professor Drennan!!!

[adarshyadav]

The ejected electrons from the metal surface are also called [ Photoelectrons ]

[paullewallen]

This lecture is a great supplement to my courses at community college.

I literally came to the US after following her classes!
