- Why is the Planck constant an exact number with defined value?
33 Planck's constant relates two different types of quantities, namely energy and frequency That means it is a conversion factor which converts the units of quantities from one form to another If the units of these two quantities are separately defined, then one can use measurements to determine the value of the conversion factor
- Measuring Planck’s Constant - Physics Forums
Measuring Planck’s Constant By Martin Hackworth Historical Perspective and Physics Theory Max Planck (1858-1947) was born in Kiel Germany and attended schools in Munich and Berlin Planck was an early pioneer in the field of quantum physics
- What exactly is Plancks constant? how did they calculate it?
3 What exactly is Planck's constant? I'm a pharmacy student and I've googled this question but couldn't find an answer I'd understand It would be so great if somebody could tell me how we calculated Planck's constant in simple language so that I'd have a more accurate idea of what it is
- Interpreting E=hf: Particle, Wave Plancks Constant
The discussion revolves around the interpretation of the equation E=hf, which relates the energy of a photon to its frequency and Planck's constant Participants explore the implications of associating frequency with particles, the nature of light as both a wave and a particle, and the significance of Planck's constant within quantum mechanics
- What is the point of the reduced Plancks constant $\hbar$ (h-bar . . .
Indeed the question "Planck constant is a quantum of action But what kind of action?" has answer: "a rotation" So we understand why we have to put $2\pi$, as it refers to a complete rotation
- Why Was h Chosen for Plancks Constant? - Physics Forums
The discussion centers on the reasoning behind the choice of the symbol "h" for Planck's Constant, exploring historical and anecdotal explanations for its designation One participant inquires about the origin of the symbol "h" for Planck's Constant, suggesting it may have been randomly selected Another participant proposes that "h" stands for "Hilfsgröße," which means auxiliary quantity in
- Plancks constant, Boltzmann constant and Hawking Temperature
The Wikipedia page for the Boltzmann constant seems to mention a bit about this Notice also that in every physical equation written in the SI in which temperature appears it is accompanied by the Boltzmann constant (sometimes, hidden in another constant, such as the molar gas constant, which is just the Boltzmann constant times Avogadro's number)
- What does the unit Js of the Planck constant mean?
The discussion revolves around the meaning of the unit "Js" associated with Planck's constant, exploring its implications in quantum mechanics and its role in defining physical quantities Participants engage in clarifying misconceptions about the nature of Planck's constant and its units Some participants assert that Planck's constant is not a measure of energy, emphasizing that its units
