First recognized for 1900 by Max Planck, e bin originally di proportionality constant between di minimal increment of energy, E, of a hypothetical electrically charged oscillator inside one cavity wey contain black body radiation, and di frequency, f, of im associated electromagnetic wave. For 1905 di value E, di minimal energy increment of one hypothetical oscillator, e bin theoretically associated by Einstein with one "quantum" or minimal element of di energy of di electromagnetic wave itself. Di light quantum behave for some respects as one electrically neutral particle, as opposed to one electromagnetic wave. E later dey called di photon.

Classical statistical mechanics require di existence of h (but e no define im value). Eventually, following upon Planck's discovery, e bin recognized say physical action no fit get one arbitrary value. Instead, e must be some multiple of one very small quantity, di "quantum of action", wey dem dey call di Planck constant. Classical physics no fit explain dis fact. For many cases, like for monochromatic light or for atoms, dis quantum of action also imply say only certain energy levels dey allowed, and values wey dey in between dey forbidden.

2. When e do am?
3. Wetin be di value wey dem dey call?
4. How di light value dey behave?
5. As opposed to wetin?
6. Wetin e later dey called?
7. Who energy E originally recognize am?
8. Wetin type of action no fit get one arbitrary value?
9. Wetin e must be instead?
10. Wetin be dat also known as?
11. E get another name?
12. Wetin e be?
