State the effect of using slits of narrow width:
Would there be a wider fringe separation

if you increase s in this formula(which is slit separation) what will happen to w?(which is fringe spacing)Last edited by thefatone; 21-03-2016 at 21:45.

Always show the rearranged version in the answer to be safe.
In this case, you would say that as you decrease the slit seperation, wavelength and distance to the source remain the same, but the fringe seperation would increase meaning that the bright fringes would be observed further apart.
You can also state the relationship between the two variables for example you could say that slit seperation and fringe seperation are inversely proportional.
