Does fringe spacing increase or decrease when 'the screen is moved further away from the slits'? :P

If λ is increased the spacing will be larger

If L is increased the spacing will be larger

If the spacing between the two slits is reduced the spacing will be larger

Just use the formula w=λL/d

It makes it much easier if you just know that W(fringe spacing) is proportional to screen distance and wavelength, and inversely proportional to slit distance

0.o Diffraction only changes when the modify the width of the slits. Slit-screen distance and distance between the two slits don't affect diffraction.

I was about to say this. They've all answered if the fringe spacing changes.
