Homework Help: Decreasing the distance between the wave sources...

  1. Feb 6, 2017 #1
    1. The problem statement, all variables and given/known data
    Imagine a interference pattern like the common water-wave interference pattern.

    What effect would decreasing the distance between the 2 wave sources have on the interference pattern?

    2. Relevant equations

    3. The attempt at a solution
    A change in the distance between the two sources will also alter the number of lines. When the distance is decreased between the wave sources the interference pattern will become larger ( larger diffraction ) and the angles between the nodal lines would become greater, and the wavelength of the resulting waves would also decrease.

    I'm not very confident in my answer. I tried to visualize this in my mind but it was difficult. I tried to look for some ripple simulations to help me but I couldn't find one.

    Is my answer correct? I tried to visualize it but I just couldn't. I just took examples from my book and compared them.

    I'm I missing anything important or am I wrong? Thank you in advanced.

    I think you are correct i.e. the wavelength will decrease.
    If they are brought closer then the distance will decrease and so, perhaps the wavelength will decrease.
    Mind you, this is only a supposition.

    Hmm is there anything else I can add/ know of a simulator that can prove my statement?

    Sorry I'm a bit of perfectionist.

    Thank you for the help too.
