    I have a test tomorrow buy my teacher said it's m - 1/2

    Why does it say n + 1/2 everywhere. >_<

    What is m in this equation? (both according to your teacher and to the other sources you found)

    According to my teacher n is the number of spots from the center (dark or light).

    Here's one of my other source.

    From your source, m is an integer 0,1,2...
    This means that the equation simplyfies into [itex](\frac{1}{2})\gamma =dsin(\theta)[/itex], [itex](\frac{3}{2})\gamma =dsin(\theta)[/itex], [itex](\frac{5}{2})\gamma =dsin(\theta)[/itex]....

    From your teacher, the number of spots away from the center is n.

    So the first spot would yield [itex](\frac{1}{2})\gamma =dsin(\theta)[/itex], the second would be [itex](\frac{3}{2})\gamma =dsin(\theta)[/itex], and the third would be [itex](\frac{5}{2})\gamma =dsin(\theta)[/itex].

    Do you see where I'm going with this?
