First recognized in 1900 by Max Planck, it was originally the proportionality constant between the minimal increment of energy, E, of a hypothetical electrically charged oscillator in a cavity that contained black body radiation, and the frequency, f, of its associated electromagnetic wave. In 1905 the value E, the minimal energy increment of a hypothetical oscillator, was theoretically associated by Einstein with a "quantum" or minimal element of the energy of the electromagnetic wave itself. The light quantum behaved in some respects as an electrically neutral particle, as opposed to an electromagnetic wave. It was eventually called the photon.
What is considered the minimal energy increment of a hypothetical oscillator? In what year was the value E associated by Einstein with quantum theories of energy? Who discovered an association between the value E and quantum energy? What did the light quantum behave the same as in laboratory experiments? What type of charge did a particle have that behaved similarly to light quantum energy? What is energy abbreviated to in science? What is frequency also known as in science? What term describes a small amount of element? What did the light quantum, in some ways, behave as? What was later termed the photon? When did Max Planck first recognize the value of the Planck constant? Which scientist associated the Planck constant with a quantum five years after Planck's recognition? Instead of an electromagnetic wave, what did the light quantum behave as in some regards? What is the simple name given to the light quantum today?
