Thank you, i get it now.

For example if i need to find distance between centre and third minimum(third dark spot)k=3, i know i have to use Δx= 5λ/2 and then i can derive it from this formula, but if i try to write it using this formula Δx=(2k+1)*λ/2, i get that Δx=7λ/2.

Hello guys i have one problem and i can't find right solution. In some notebooks for destructive interference it says Δx=(2k+1)*λ/2, and it doesn't make sense for me because if i insert k=1 it will be 3λ/2 and it should be λ/2. And also for light diffraction d/2sinθ =λ/2, this one is correct...
