Fresnel Equations at Normal Incidence

If you've felt like the content here has been helpful, please consider donating to UCI with a mention of this channel: https://give.uci.edu/ Probably the most important equations in optics, the Fresnel equations allow us to figure out how much of an electromagnetic wave is reflected off a surface - and this gives us immeasurable power to design waveguides, mirrors, and all manner of optical devices. This is part of my graduate series on optoelectronics / photonics, and is based primarily on Coldren's book on Lasers as well as graduate-level coursework I have taken in the EECS department at UC Berkeley.
