What is the Ultraviolet Catastrophe?
Physics Explained・2 minutes read
Physics in the late 19th century saw advancements in thermodynamics and electricity with Maxwell's unification of electricity and magnetism revealing light as an electromagnetic wave. Max Planck's introduction of energy quantization to solve the ultraviolet catastrophe issue revolutionized physics, leading to the birth of quantum mechanics.
Insights
- Max Planck's introduction of energy quantization revolutionized physics, solving the ultraviolet catastrophe and leading to the birth of quantum mechanics by proposing energy as proportional to frequency with the constant h.
- Physicists applied electromagnetism and statistical thermodynamics to derive spectral radiance functions for black body radiation, with relationships between wavelength, frequency, and energy states in different dimensions, ultimately establishing laws relating radiation intensity to temperature and peak emission wavelength.
