WebPlanck figured out that energy was quantised when trying to explain black body radiation. At the time, the classical theory predicted that a body would radiate an infinite amount of power, which is obviously wrong. Planck found that by assuming the mode excitations were quantized he got a convergent answer. WebPlanck’s contributions appear to be comparatively simple: the addition of the –1 term in the denominator and the definition of the constant h. However, the derivation was quite complex, and the relationships associated with these constants have deep implications.
