The basic quantum constant h, known as Planck's constant,and its value is 6.626 x 10 -34 Js The quantum theory of physics was developed in order to explain the relationship between matter and energy at an atomic level as well as subatomic. The theory was created by the ideas of Max Planck, Albert Einstein, Niels Bohr, Werner, and many others. It includes basic ideas of quantum physics. One of the most prominent ideas is that matter acts as waves AND as a particle (wave-particle duality).
