Physical Meaning of Planck's Constant

The photon energy with its corresponding frequency, wavelength and distance can be determined by the main physical parameters (mass, distance, time) of the particles (electron, nucleon, molecule) as a result of their excitation, transition, vibration and rotation. The Planck’s constant is interpreted which represents three main physical parameters (mass, distance, time) as a result of the physical mechanisms responsible for excited states of nuclei, atoms and molecules. As a result of equality between Planck’s constant and the mentioned three physical parameters a new equation of calculating exact distance of all photons from nuclei, atoms and molecules from radio waves to gamma rays is deduced.
