Planck's constant describes the ratio between the energy of an electromagnetic wave and the frequency of that wave.
Planck's Constant defines a minimum momentum moment h=mvw where w is wavelength. Planck's Constant is the product of electric charge Q and magnetic charge W (Weber voltsecond). The Planck energy E=...
Energy/frequency or energy*wavelength/speed of light.
Albert Enstein was the first person to use Planck's theory
New technology causes scientists to question existing theories.
