De Broglie & Bohr: Electron Kinetic Energy Formula

[matsorz]

An electron around a hydrogen-atom, with radius r and length of circle a whole number, n, times wavelength. This implies that
2*3,14*r=n*(wavelength)

I have read someplace that if you substitute the wavelength with h/p, you can find the kinetic energy of an electron, which is the same as Bohrs formula for energy.

Anyone here that can help

Bohr's discussion of the atom was a predecessor of Schrödinger quantum mechanics. It happened to give the right energy levels for hydrogen, but is wrong in other details, for example the multiplicity of the levels. Unfortunate that it is still taught.
