Quantum machanics is a framework that make us to describe motions and energy of small neglected mass wave-praticles .
It describe motions of point mass and behavior inside atoms or out side the atom
Like election,proton,nutron etc
beginning of quantum machanics??
Max planck by studying black body readiation give a expression for light wave i.e light energy travel in energy packets and energy is directly prpotonal to frequency
De-brogle give a hypothetical assume that praticles
Also behaves like wave and by experiment it is proved
By devation-germar experiment .
Nil Bohr give a new framework useing de-brogle equation which is describe hydrogen atom more flexibly than before framework and win Nobel prize for this
According to this theory election are revolving around nucleus in a certain orbit .called permitted orbit which is integral multiple of wave length. And in this they don't radiate energy and also give expression for position and momentum which is mostly describe everything of an atom .and experiment proof that it is true and every series of spectral line in accordance with Bohr theory
Everything changed when hygenberg give a new revolutionary proof that is ""practicle positions momentum is can't be known simoltinusly known as uncertain principal
And the equation is
The above equation proof de-brogle wave equation which is source of nil Bohr framework which voilate the above equation.
Bcz Bohr model describe position and momentum can be known .but uncertain principal don't obeying it
So it tends to believe that Neill Bohr was wrong.
Then interduce a new frame work by scondizer
It is well know n machanics called quantum machanic
Quantum mechanical hydrogen atom
Bohr hydrogen atom
You can see the difference
