- H-alpha -> 656.3 nm
Information
Hot hydrogen emits light in a set of spectral lines. Balmer series set of lines in the visible spectrum.
Bohr’s Model of Hydrogen Atom
A small negatively charged electron orbits a small positively charged core (the proton) like a planet around a sun but with electrostatic attraction.
Key
Angular momentum is “quantized” in units of Planck’s constant, , over . (Neils Bohr, 1913)
de Broglie Hypothesis

A particle with mass also behaves as a wave with wavelength. Particle’s Momentum
