答案为:(1) ;Evaluation only. Created with Aspose.Slides for .NET 3.5 Client Profile 5.2.0.0. Copyright 2004-2011 Aspose Pty Ltd.; 分析条纹的移动方向时,常跟踪视场中的某一级条纹观察它朝什么方向移动,则其它条纹相应的也朝这一方向移动。 若考虑光源S在两缝的中垂线线上,则光程差为零的中央明条纹(零级明纹)的中心在两缝的中垂面上。若S下移,现在要使得双缝发出的光程差仍为零,两束光必须在中垂面的上方相遇。 即零级明条纹上移,其它条纹也随之上移。 ;答案为:(2) ;Evaluation only.
