Properties of Light: Blackbody Radiation

TRIGGER WARNING:  In my youth and foolishness, I committed the grave and unforgivable sin of saying (shudder) "degrees Kelvin" rather than just "Kelvin", as a morally upright person would.  Several people, paragons of trivial minutiae, have correctly pointed this out in the comments and reached the obvious conclusion that this error invalidates the other nine minutes and fifty seven seconds of this ten minute video.  I, humbly and with a penitent heart, prostrate myself before these sages of technicalities, and, in wailing lamentations, beg forgiveness for my folly, which clearly made the entire rest of the video unintelligible.  To others who would read this, be warned, it's just "Kelvin".  To add "degrees" in front of that is madness.

A look at the property where, at high temperatures, objects will begin to glow and the spectrum of the light they emit will depend on temperature.  This can be used to measure the temperature of distant objects.  Part of an introductory series on astronomy
