1They are bohr's equations itself .....and i think it's used for forming questions for exams only......(i may not be correct...)
It is well known that, "Neil bohr failed in his model in which he described an electron as a charged particle moving in well defined circular orbits about the nucleus." However he failed because of the two major reasons..
a) It didn't consider the wave nature of the electrons
b) contradicts the uncertainity principle (which is true for microscopic particles).
so if the orbits are not "properly defined", whey then do we use the formula for the electrons in the nth orbit of a Hydrogen atom like...
the energy of an electron in the nth orbit = -RH (1/n2)
Radius of an electron in the nth orbit = a0 n2
i mean "if the theory of existence of such well defined trajectories is meaningless" then why not the formulas????
