Quantum Physics - Part 1 (Blackbody radiation, Wien's Displacement Law, Planck's Law)

In 1900, Max Planck worked out the relationship between the radiation emitted by a blackbody as a function of temperature and wavelength, and in doing so started a whole new branch of physics.

9:36 - Review

In reality, the equation Planck came up with was much more complicated since it involved Intensity as a function of two variables, but we are focusing on the idea that energy had to be a discrete value instead of any value as was previously thought.
