Equation IV-3 therefore provides us a way of measuring Planck's constant. If we know the frequency of the light emitted from the LED and we can measure the diffusion potential, then h/e is given by Eq. IV-3. However you will be finding the wavelength of the light, not its frequency. Since you know that νλ= c, Eq. IV-3 can be rewritten: VD = hc e

Equations 1 and 2 show why Planck’s constant is linked with the quantization of physical quantities like momentum and energy. Natural formulas clearly articulate two distinct levels of quantization that were described by Planck and Einstein in terms of Planck’s constant [6] [7]. The quantization of energy for a

Progress is made every year in measuring Planck’s constant; however, little progress has been made in understanding its nature. Planck’s constant is thought to be a fundamental physical constant defined in the realm of quantum

Planck’s Constant 5.1 Introduction The emission and absorption of light was an early subject for investigation by the Ger-man physicist Max Planck. As he attempted to formulate a theory to explain the spectral distribution of emitted light based on a classical wave model, he ran into considerable difficulty.

Planck’s constant h=6.626 070 15*10-34 kg m2/s. This is the result of advances in metrology: The best two measurements of h, the Watt balance and the silicon spheres, have now reached an accuracy similar to the mass drift of the ur-kilogram in Paris over 130 years. At this point, the General Conference

The method used for determining the constant is called the photoelectric effect; something that Einstein received the Nobel Prize for explaining.

The discovery of the Planck’s relation is generally regarded as the starting point of quantum physics. The Planck’s constant h is now regarded as one of the most important universal constants. The physical nature of h, however, has not been well understood. It was originally suggested as a fitting constant to explain the black-body radiation.
