Planck and black body radiation

One of the remaining problems in physics was the “ultraviolet catastrophe” – the predication that output radiation intensity would increase indefinitely at shorter wavelengths. This was in disagreement with both observation and the conservation of energy. Planck’s proposal of quantised energy levels within the black body provided some answer to this problem, and inadvertently began a new field of physics.

These slides outline the ultraviolet catastrophe and Planck’s contribution, including the relation E=hf.
