## Resource

Explore how the theoretical concept of a black body exposed the fundamental failures of classical physics. Learn how Max Planck's study of radiation led to the birth of quantum mechanics.

## Highlights
- Main idea: A black body is a theoretical object defined by its perfect absorption and emission of electromagnetic radiation
- Main idea: Black body radiation intensity is directly linked to temperature, similar to how stars or molten lava glow
- Technical concept: The electromagnetic spectrum is characterized by the relationship between wavelength, frequency, and energy
- Failure mode: Classical physics was unable to explain the properties of black body radiation, creating a crisis in the field
- Practical takeaway: Planck's formula introduced essential constants like Planck's constant (h) and the Boltzmann constant (k) to explain energy quantization

## Topics

Black Body Radiation, Quantum Physics, Max Planck, Electromagnetic Spectrum, Planck's Constant, Classical Physics, Thermodynamics, Wave-Particle Duality
