Heat Transfer - Radiation
How is it possible that we can feel the heat of a sun that is so far from Earth? Study the type of heat transfer that makes this possible! The video introduces learners to radiation and how it functions when transferring heat.
Berkeley University of California
Absorption and Emission Spectra
How does quantization affect absorption and emission? The instructor explains how creating boundaries for a particle that behaves like a wave creates quantization. This is the property that allows for the absorption and emission of...

Bozeman Science: Emission or Absorption Spectra
In the following video Paul Andersen explains how the photons emitted from or absorbed by an atom or nuclei is directly related to electrons moving between energy level. Absorption and emission are a direct result of the conservation of...

Bozeman Science: Stimulated Emission
In the following video Paul Andersen explains how stimulated emission can be used to create coherent light. When an atom absorbs a photon it moves to a higher energy level through stimulated absorption. It may then release a photon and...
