Geometrical, Wave, Physical, Quantum & Modern Optics: Famous Expents, Effects, Applications & Mathematical Models What you'll learn Geometrical optics: Reflection & Refraction for understanding Mirrors & Lenses Wave optics: Diffraction, Interference & Polarization of light as a wave explained by Huygens' principle & Electrodynamics Quantum optics: Energy, Momentum & Spin of light as photons Famous expents: Double-slit expent, Photoelectric effect, Compton effect & many more Solar cells & LASER as modern light technologies Mathematical descriptions and derivations: From Maxwell's equations to Fresnel equations Exercises and applications of cool phenomena like Birefringence & Dichroism Modern optics phenomena like Holography & Fourier optics Requirements Basic mathematics Recommended: What are derivatives and vectors? Description This course is for everyone who wants to learn about optics: Bners to experts!A bit of high school mathematics (trigonometry, equations) is all you need to know to get started!The fundamental question of optics is: 'What is light?' Is light a ray or a beam that can be fully described by geometry? Is light a wave that can interfere with other waves and can bend around corners? Does light consist of particles that have an energy and a momentum just like electrons or even macroscopic objects like a football? Here, we will discuss all of these approaches based on theory and expents. I can guarantee that you will learn a lot no matter what your current skill level is. For advanced students: The later lectures about wave and quantum optics are on a university level.You are kindly invited to join this carefully prepared course in which we derive the following concepts from scratch. I will present examples and have prepared quizzes and exercises for all topics.Geometrical optics (3 hours)Reflection & MirrorsRefraction & LensesApplications: Eye, Microscope & TelescopeWave optics (or physical optics) (8.5 hours)Expents & Phenomenological description (incl. introduction about derivatives and differential equations)Diffraction, interference & PolarizationTheory based on Maxwell’s equations (incl. introduction to complex numbers)Electromagnetic waves in matter: Derivation of the Fresnel equations & Complex refractive indicesQuantum optics (4.5 hours)Photons: Quantum description of light (Photoelectric effect, Compton effect)Applications: LASER & Solar cellIntroduction to quantum mechanicsOutlook: Modern optics phenomenaWhy me?My name is Borge Gobel and I am a postdoc working as a scientist in theoretical physics. Therefore, I use presented concepts very often but I have not forgotten the when I learned about it and still remember the problems that I and other students had. I have refined my advisor skills as a tutor of Bachelor, Master and PhD students in theoretical physics and have other successful courses here on Udemy.I hope you are excited and I kindly welcome you to our course!
