【摘要】 半波损失是大学物理中的重点和难点问题。根据半波损失定义明确了其产生条件,重申了半波损失和附加光程差的区别与联系,并结合薄膜干涉实例对附加光程差表达式作了针对性的分析,即附加光程差项可以取正号,也可以取负号,只是为了满足干涉级序数从零开始取值。更多还原

【Abstract】 Half-wave loss is the key and difficult problem in university physics. In this paper,the conditions of the half-wave loss are defined,and the difference between the half-wave loss and the additional optical path difference is reaffirmed. Finally,the expression of the optical path difference is analyzed with the example of thin film interference.更多还原
