ANiels Bohr
BIsaac Newton
CJohann Balmer
DMax Planck
Answer & Solution
Correct answer: D. Max Planck
1. The ultraviolet catastrophe stood until someone changed an assumption about energy.
2. Finally, around 1900, Max Planck derived a theoretical expression for blackbody radiation.
3. It fit the experimental observations exactly, within experimental error.
4. Bohr later built on Planck's ideas of quantisation when modelling the atom.
