I'll work through the question in a minute and see.

If you can keep your head when all about you
Are losing theirs and blaming it on you,
If you can trust yourself when all men doubt you
But make allowance for their doubting too,
If you can wait and not be tired by waiting,
Or being lied about, don't deal in lies,
Or being hated, don't give way to hating,
And yet don't look too good, nor talk too wise:
Yours is the Earth and everything that's in it,
And--which is more--you'll be a Man, my son!

There are 11 fringes, so there are 10 spaces between the finges. so delta X = 0.0026 m
d=0.52 x 10 -3 m
D = 2.00m
delta (X) = lambda (D)/d
lambda = delta (X) d/D

In my class we did unit 3 first and then unit 1, so we are currently doing unit 2 which I think is probably the hardest unit, although it's not too bad.
We just have self inductance to do.
500 posts and counting.

Have you done question 11(iii) in the 2003 Exam ? My course notes (both Scholar and other) have no examples like this. Is it a problem solving question? Any help would be great.
Has everyone finished their Investigations ?
Thanks.

That's not problem solving and is definitely in the course.
When light enters are more optically dense media such as glass or perspex it undergoes a change of phase of

I've finished my physics investigation, just need some final checking, I emailed my teacher with it yesterday and she should get back to me on Monday about it. What is everyone's investigation on? Mine is on the physics of stretched strings.

I have never heard about this - is there anything else I should have been given and will we be able to use this booklet in the exam and NABs ?
