Photon Energy and Photoelectric Equation

The handbook opens Atomic Structure with Planck's quantum relation and photoelectric effect.

Energy of one photon

E=h\nu=\frac{hc}{\lambda}

Photoelectric effect

h\nu=h\nu_0+\frac{1}{2}m_ev^2

$h$

Planck constant

$\nu$

frequency

$\lambda$

wavelength
