“Adore Planck’s constant as if it were a new god,” I think that’s what I heard when I was studying or at least, I would have imagined.
In quantum mechanics there is a magic number, Planck’s constant which varies according to the supplied units. What is its value and because it is essential ?. Simply because the energy associated with the frequency of a wave.
Come on, you obviously know that the hotter something stronger vibe. The typical example (not correct, but as an idea worth) is to see how when something in a saucepan cook it moves as if he were a glow (well, are the currents of conviction, but as an example we had better).
The trick is in knowing that each object, including the smallest, atoms and elements have energy states. Example is an electron, although at that scale many equations collapse so rough they are (eg between an electron and the nucleus gravity acts but an electron does not quite gotten into the nucleus by electrostatic repulsion and, interestingly, not out shot out for something that I will tell you) and you have to “improve” these equations so that these small phenomena that make us “Lokers” (crazy) are included.
An electron, as I told you, is influenced by several things. The severity of the center, the repulsion of the center itself (remember, electrons, neutrons and protons, negatively charged electrons and positively charged protons) by electromagnetic radiation and, in addition, protons including out not fired like electrons, what things!.
The fact is that all that is attached (because otherwise we would loose particles in the universe and think not).
Electrons revolve around the atom, then if they rotate as physics is universal to any size (yes, although you may not believe, another thing is that the equations are better or worse) it means that, as everything revolves, it must have an angular momentum … and has.
Although not I have told you, electrons have different “orbits” (not in the strict sense) or rather distances that are at the core depending on their energy, then they will have different times. How do we know the time or the energy that an electron this ?. Well simple, we see that energy is: E = pc + mc ^ 2 where p is the time, c the speed of light and E the energy, this must be added the electron mass and the speed of this, let energy kinetics.
Playing with that term, known by everyone in the school, eventually we arrived to the energy of an electron is E = hf or frequency by a number that is Planck’s constant. The trick is to remember simply that the electron has no mass (if, that is, but it’s negligible, as my hair).
From the moment we can draw many interesting things (if we play with another relationship more, it is to know which is the frequency.
In fact, if we play a lot here we get to demonstrate the principle of indeterminacy because really what you can do is or determine the electron’s momentum or the position of this (not the speed and position) that helps us see the model as a electron cloud or play with the theme of stoking the electron with a much finer wave.
Before I forget, and I start chive grandfather, is seen as from Planck’s constant will leaving many others. That is, Planck’s constant is the basis of many other constants, such as Faraday, the Avogadro (do I spell it ok?) … let Planck’s constant is the basis of many things and therefore of many other constants.
