Chp Wave optics topic ; optical path
Meritnation please tell me why that encircled part is zero for the third question
please help
Dear Student
The point O on the screen lies on the perpendicular bisector of S1 and S2. Therefore, the path difference between two waves reaching O is zero and hence, they are in phase. So S1O -S2O =0
So, the point O is the position of maximum intensity. It is called central maximum.
