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 $d\sin(\theta)=m\lambda$

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.
