Planck's Hypothesis: Quantized Energy
Captions available
The idea
Max Planck resolved the blackbody puzzle by proposing energy is exchanged in discrete packets, each with energy equal to Planck's constant times frequency, E = hν.
In practice
Restricting a vibrating source to discrete energy packets, rather than continuous values, correctly predicted the observed blackbody curves.
Where people slip
Planck's quantized packets describe how energy is exchanged, not a claim that energy is literally countable pieces.
