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. 0:00 - Intro 0:47 - What is a blackbody? 1:26 - Radiation and temperature 2:27 - How the experiment worked, the Stefan-Boltzmann Law 3:58 - Wien's Displacement Law and the relationship b/w temperature and wavelength 5:12 - Rayleigh-Jeans Law and Wien's Distribution, why they didn't work 6:51 - How Planck derived his Law 8:22 - Energy is discrete, not continuous 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.
