    i can't do b part 1 since i'm too inept ;( although i should know how to do it....

    a part 2 though
     \omega = \dfrac {\lambda D}{s}

    so if you increase s for example  \lambda would get smaller and the fringe spacing would get smaller? so the pattern on the graph would have a lower frequency? so slit width is bigger than wavelength of light? i'm really not sure but it's somewhere to start i guess

    then you got part 3
     \omega = \dfrac {\lambda D}{s}
    so increase s decrease w right?

    Thanks for the reply but what does w and s stand for cause I don't learn the formula using those letters

    w = fringe spacing in metres (m)
     \lambda = wavelength of the light in metres (m)
    D = distance between the double slits and the screen in metres (m)
    s = slit separation in metres (m)
