Answer:
The pattern would spread out.
Explanation:
The fringe width is given by the relation
fringe width = λ L / D where λ is wavelength of light used, L is distance of wall from the source of light and D is slit separation.
If we increase λ , fringe width will increase and therefore pattern will spread out .
I think its D but I'm not sure :/
