Homework Help: Nodal lines

  1. Oct 28, 2007 #1
    1. The problem statement, all variables and given/known data

    In a two - point in phase inteference pattern, what will happen to the number of nodal lines if the wavelength of the two sources increases? Justify your answer

    2. Relevant equations

    Not too sure if an equation is needed to answer this question

    3. The attempt at a solution

    I said they would stay the same but its wrong.

    as the wavelength increases there will be more more nodal lines as the frequency will also increase. with faster wavelenghts the frequency will increase which means the waves will be shorter which will allow for more destructive interference which are nodal lines.
