Young's experiment question

Hy!
I have a problem with one question about Young's experiment.
I'm aware this is not really apropriate place to ask but I'm in a hurry
so if anybody knows help me!
Don't know how to solve this :
In Young's experiment with 2 slits and monochromatic light
( L=500nm )we have result with many maximums.
In same experiment we put a thin transparent material (with n=1.6 )
behind one slit. Then zero maximum is at the same place where 15th
maximum in 1st experiment was.
Find the thickness of transparent material.
Now, I know this material somehow changes the waves that go through
but i don't know how - is the phase different ?
Or this material just translates the wave?
If so, for given angle I can calculate the translation, but what angle?
Please help!
