Atomic radiation

Electron movement	Pictures	Formula
Electron goes outside of atom		${\displaystyle hf=hf_{o}+{\frac {1}{2}}mv^{2}}$ ${\displaystyle v={\sqrt {{\frac {2}{m}}(hf-hf_{o})}}={\sqrt {{\frac {2}{m}}nhf_{o}}}}$ Để có ${\displaystyle v>0}$ , ${\displaystyle f>f_{o}}$
Electron goes inside of atom		${\displaystyle nhf=mvr(2\pi )}$ ${\displaystyle v=({\frac {1}{2\pi }})({\frac {nhf}{mr}})}$ ${\displaystyle r=({\frac {1}{2\pi }})({\frac {nhf}{mv}})}$ ${\displaystyle n=2\pi r({\frac {mv}{hf}})}$
