Homework Statement
This isn't really an actual homework question but it is regarding a lab so I think it belongs here. In the ripple tank lab I have to trace the nodal lines, plot 3 points in the middle of the 2 lines (one closest to the two sources, one in the middle and one the farthest). From there I use |PnS1-PnS1| = (n-1/2) λ and Xn/L = [(n-1/2) λ]/d to find λ and then compare the values I get with my partner's and explain why some are outliers.
Homework Equations
Why is Xn/L = [(n-1/2) λ]/d not as good as |PnS1-PnS1| = (n-1/2) λ when calculating λ?
The Attempt at a Solution
I think it has something to do with (n-1/2)λ/d not quite equalling 1 but I still don't understand this.
Any and all help would be appreciated!
