物理教学中氢原子巴耳末系光谱的两种观测方案

Two schemes for observing Balmer Series of hydrogen atom spectrum in physics teaching

观测氢原子光谱巴耳末系的实验能够对氢原子光谱实验规律的教学提供实验支持。本文以高中物理教材文本作为实验方案的设计线索,基于棱镜分光计和光栅,提供两种观测氢原子光谱巴耳末系的简便易行的演示实验方案,并分析两种方案的优缺点,以丰富"氢原子光谱"的教学资源,为氢原子光谱教学提供参考。

In high school physics teaching,setting up the experiment of observing the hydrogen atom spectrum Balmer Series can provide experimental support for the teaching of hydrogen spectrum experiment regularity.Based on the prism spectrophotometer and optical grating,respectively,using the high school physics textbook as a clue of design o{ the experiment scheme,two easily-operated experiment schemes of observing hydrogen atomic spectrum Balmer system have been provided in this paper.The advantages and disadvantages of the two schemes have been also analyzed.These two experiment schemes will enrich the teaching resources of ＂hydrogen atom spectroscopy＂ and provide reference for the hydrogen atom spectrum in physics teaching.
