It can then happen that electrons are released from the atoms due to the energy of the light. However, this experiment produces some unexpected results that can only be explained if the light is interpreted as a particle. In this video, the experiment and the physics behind the photoelectric effect are explained as simply as possible. It also shows how you can calculate the kinetic energy of the individual electrons.

If you buy one of my book recommendations via the Amazon links below, I will receive a small commission as an Amazon partner. These two textbooks are the standard literature for starting your physics studies. I was personally very satisfied with the second book in the series on electricity and optics, and I still use it often today to look up certain topics. I only bought the first book at the end of the first semester, so I didn't use it that often, but it helped me a lot with certain topics for exam preparation! The books are also suitable for preparing for your studies before you start, especially since there are tasks at the end of each chapter, and the solutions to these tasks are also at the back of the book. (I would probably skip the first chapter of the book Experimental Physics 1) ▶︎ Experimental Physics 1: Mechanics & Heat by Wolfgang Demtröder Amazon link: https://amzn.to/3DQBADP ▶︎ Experimental Physics 2: Electricity and Optics by Wolfgang Demtröder Amazon link: https://amzn.to/3DYgnaX After the first year of your studies, you continue with in-depth courses on theoretical mechanics, quantum mechanics and electrodynamics & statistical physics (thermodynamics). My book recommendations on these topics are partly in German and partly in English. This is because sooner or later (at the latest during the master's program) all lectures are held in English. I have also had very good experiences with all of these books myself! ▶︎ Classical Mechanics by John R. Taylor Amazon link: https://amzn.to/3r5Eixw ▶︎ Modern Quantum Mechanics by JJ Sakurai Amazon link: https://amzn.to/3UFvJa9 I mainly used this book for my first course on quantum mechanics and was very satisfied. ▶︎ Introduction to Quantum Mechanics by David J. Griffiths Amazon link: https://amzn.to/3BMZc9w As an alternative to Sakurai's book, I also ordered this book and can definitely recommend it. All of the important topics are covered, but I would tend to go for the other option. ▶︎ Introduction to Electrodynamics by David J. Griffiths Amazon link: https://amzn.to/3LIjPbw Thanks for watching!
