Tour of the Electromagnetic Spectrum: Visible Light

See just how narrow the visible light band is relative to other EM energy – and why, despite that, it’s crucially important to humans. Explore the relationship between color and temperature, the appearance of the atmosphere (and why the sky is blue!), and how scientists use light scattering to figure out what things are made of - both on and off Earth - in this video from NASA.
