ATOMIC SHELLS

目的：记录和解释巴尔默系列氢谱线在可见光区的谱线。 发光原子的线光谱是每个特定化学元素的唯一特征，尽管它们对于原子序数较高的元素变得越来越复杂。相比之下，位于可见区域内的氢原子谱线的一部分可以简单地基于原子的玻尔模型来解释。 另外推荐：补充ue5020100s 更多

Objective: Record and interpret the Balmer series of lines for hydrogen other line spectra in the visible region The line spectra of light-emitting atoms are uniquely characteristic for each specific chemical element, although they become ... 更多

Objective: Carry out high-precision measurements of absorption and emission lines The resolution of a spectrometer is often assessed in terms of whether the two sodium D-lines can be distinguished. This experiment uses a digital spectrometer ... 更多

•  Record and evaluate the Franck-Hertz curve for neon and observe emission of light. •  Compare the distribution of current maxima with the excitation energies of neon atoms. •  Observe the light ... 更多

•  Measure the collector current IR as a function of the accelerating voltage UA. •  Compare the positions of the current maxima with the known critical potentials of the helium atom. •  Identify ... 更多
