Right so I've been stuck with this for a while now and I'm sure it's just something simple that I've missed. Right so the question says there are a pair of closely spaced slits (0.300mm apart). By changing the spacing the bright fringe moves from position m=2 to m=3. The wavelength remains constant. And that is all the information given in the question.
ym=R(mλ/d)
So I've been given m and d but I don't have ym or R (being the distance between the screen and the slits).
I would be very grateful if someone could be help find ym or R. Thanks
