Max Planck By: PuneetSekhon and Navreet Brar
Personal Life of Planck • Born in Kiel, Holstein on April 23/ 1858 • Would have become a musician • Studied at the University of Munich • Won a Nobel Prize in 1918 • Married twice in his lifetime; had five children • Died in Gottingen, Germany on October 4, 1947
Idea of the Atom • Atoms absorb and emit energy in bundles, called quanta, instead of in a continuous wave. This theory was called the quantum theory. • Equation for one quanta: • E=hv; (E = energy, v = frequency, h= a very tiny proportionality constant) • H= 6.626 x 1034; reflects the size of one quanta.
Area of Study • Area of study was physics, interested in relationship of heat and radiation • Plank’s law: a law that explains that certain wavelength is radiated by a black body at the same temperature • Using the Plank’s law, Max Planck described the black body radiation, by proposing that electromagnetic radiation was emitted in quanta.
Major Scientific Contribution • Discovered quantum physics • Law of heat radiation, named Planck's law of black body radiation. • Developed Planck’s law • Discovered Plank’s constant, E = hv (the h = 6.626 x 1034)
