Homework Help: Young's Double Slit Experiment in Water

  1. Sep 27, 2011 #1
    1. The problem statement, all variables and given/known data
    If Young's double-slit experiment were submerged in water, how would the fringe pattern be changed?

    2. Relevant equations
    None...but maybe [itex]d\sin(\theta)=m\lambda[/itex]

    3. The attempt at a solution
    It would not because the waves still propagate in the same manner and the wavefronts are still circular.

    Doesn't the wavelength change in water?

    I do not think that is the formula to be used.

    I just found the answer, the wavelength does shorten in water, so the fringes would become closer together.
