Blackbody Radiation Questions 3,4: Comparing Planck's Law to Rayleigh-Jeans Law for the Sun https://youtu.be/SL3z_KJ7yPw

In this video I graph out the blackbody radiation energy density for the Sun using both Planck's Law and the classical Rayleigh-Jeans Law. At high wavelengths, both models are similar but at low wavelengths the classical theory diverges wildly to infinity. This was the cause of the Ultraviolet Catastrophe.
