    Stalker it is xD

    Quite confident, but it could go awfully if its not a nice paper. You?

    Everywhere as in bio, chem, physics, maths threads :P (if I'm not mistaken). I think we took a lot of the same exams

    putting aside the sexual favours here goes:

    lets say the distance between the centre of 2 adjacent slits is 'd' which can be worked out by doing  \frac{1}{no.of.slits.per.metre}. so as the wavefront of the source comes in, it diffracts at an angle  \theta towards the screen, this can be calculated by using a protractor or a spectrometer. if you get constructive interference you know that the path difference for say the first order is  \lambda. now using some trig, we know that  sin\theta = \frac{opposite}{hypotenuse} . sub in  \lambda and 'd' to give  sin\theta = \frac{\lambda}{d} . which gives  dsin\theta = \lambda . now for every maxima or order on the screen, that means you are getting constructive interfence, therefore the path difference with always have to be a whole number (integer) multiple of  \lambda, so lets call that  n\lambda. therefore you get  dsin\theta = n\lambda


    on the diagram A to C represent  \lambda
    Sweet, thank you for that explanation, in my book, I can follow it up to the dsin(theta) part, but I don't understand how to explain the part with the n in words, and you've just done that, thanks a lot buddy!

    Sorry, I just ate my crappy chicken wraps. I am very confident for the exam. Just had ICT exam today. And, sorry, I have never posted anything on the biology section chemistry section. But yeah, maths physics a lot of times.
