1913 Bohr proposed an atomic model can be used to explain the hydrogen atom spectrum, summarized its content as following:
atom electron spin around the nucleus;
electron motion orbit quantization;
the electron acceleration, but not radiation energy;;
when jump from the upper state to launch low-energy state, electromagnetic wave and light spectrum are produced, frequency ΔE / h ,The experiments show that the hydrogen atom spectrum obtained three spectral series:
Lyman series; Balmer series; Parsons Series
But only Balmer series is in visible,thus,this experiment is carried out in this series of observations and measurements.
Experiment:
grating splitting the light hydrogen, Balmer series spectra obtained.
measure wavelength λ by experimental methods;
Find h (Planck constant).
Specifications:
hydrogen lamp and power; spectral wavelength 410.2,434.0,486.1,656.3.
one slit, the smallest gap is about 0.09mm.
