    Hiya!

    I have questions that i am hoping someone can confirm my answers to, plz.

    1) In youngs double split experiment, if the seperation between the slits decreased wouldnt the distance increase between the interference fringes? I say yes, i used this formula to derive my conclusion. sin[the]= m[lamb] / d. am i correct?

    2) In a single slit diffraction experiment, if the width of the slit increases wouldnt the width of the central maximum on a screen increase as well? Is this true, from the pics and what ive read i believe it is but wanted a knowledgeable opinoin on this question

    Dx,

    Homework problems go in the Homework Help forum, OK? These questions ain't theoretical physics.

    Yes.

    Look at the formula for the minima and try again.
