MAX PLANCK By: Puneet Sekhon 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= x ; 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 v (the h =  Discovered Plank’s constant, E = hv (the h = x 10 34)
