Homework Statement
I'm having trouble understanding how you are supposed to decide which nodal and antinodal line numbers are supposed to be attached to the corresponding line.
Homework Equations
https://roncalliphysics.wikispaces.com/Year+13+Double+Slit+Interference
I've read this and other links, and also the information provided to complete the work.
In the school book it says anti nodal lines should be m and only m should be in the center with a value of 0.
I'm talking about these numbers here and how they apply to path difference and wavelength equations.
The Attempt at a Solution
From what I read at the link it sounds like P should be n=2...
From what I read in my school book it sounds like for P n=3...
It also gives integer values to the anti nodal lines instead of decimals.
The answer is really going to determine the grade so I need to know which one is right?
