Physics · atomic-physics

Problem

Using the Bohr model, calculate (a) the radius of the

n=3

orbit of hydrogen, (b) the energy of this level, and (c) the wavelength of the photon emitted in the

n=3 \to n=2

transition (the H-alpha line). Use

a_0 = 0.0529\;\text{nm}

E_1 = -13.6\;\text{eV}

hc = 1240\;\text{eV}\cdot\text{nm}
