Young's Double Slit Experiment in Water

[JSGandora]

Homework Statement

If Young's double-slit experiment were submerged in water, how would the fringe pattern be changed?

Homework Equations

None...but maybe $d\sin(\theta)=m\lambda$

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?

 

[grzz]

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

 

[JSGandora]

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