Light
Colors, a variation of the wavelength of light they emit, is the focus of a video that explains the different frequencies of light waves, models how our brain processes the electromagnetic radiation, and how we perceive light.

Waves
Calculating frequency is so easy it Hertz! The video begins by describing transverse and longitudinal waves, and then it explores their properties and applications. Finally, it applies this to the formulaic relationships between wave...

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...
