Not getting what this question wants to say!!! 1. Two slits are made one millimetre apart and the sreen is placed one metre away. What should the width of each slit be to obtain 10 maxima of the double slit pattern within the central maximum of the central slit pattern? My problem is that that i am not getting what this problem wants.. If someone could explain it to me briefly as this problem is important for me to work out...!! Thanks in advance....!!
