Light Emission and Absorption (Electrical Properties of Materials #6)
What is so special about silicon? Why are some materials more conductive to electricity than others? Where does static electricity come from? This 14-video lecture series introduces electronics from a materials perspective, and is based on a course which all freshman engineering students take at the National University of Singapore.
In this video:
02:02 Accelerating electrons emit light
03:59 Accelerating masses emit gravitational waves
07:14 Stable electron orbits in hydrogen
08:44 Quantization of light emission/absorption
10:17 Emission spectrum of hydrogen
14:46 Discovery of helium from the sun's spectrum
15:44 Why is space transparent?
16:57 The Epoch of Reionization
Nearly 70 additional practice problems are available in the MOOC version of this course, along with supplemental videos:
