【摘要】 在等厚干涉的实验中,加入了用劈尖干涉对比法测液体折射率的内容,在不改变劈尖膜的条件下,同时测得空气膜和液体膜的干涉条纹宽度,从而可方便地求出液体的折射率,也使得等厚干涉的实验内容更加丰富和充实.更多还原

【Abstract】 The　refractive　index　of　liquids　is　obtained　by　means　of　the　wedge　film　interference　in　the　experiment　of　the　interference　of　equal　thickness.　Without　changing　the　slope　angle　of　the　wedge　film,　the　width　of　the　interference　fringe　is　measured　when　the　wedge　film　is　filled　with　some　kind　of　liquids　and　air　respectively.　By　comparing　the　two　results,　the　refractive　index　of　the　liquid　is　easily　calculated.　The　design　of　this　experiment　enriched　the　content　of　the　interference　of　equal　thickness　and　is　suitable　to　the　establishment　of　elective　course.　更多还原
