Optics - I have no clue where to start

1. Homework Statement
See attached.


2. Homework Equations
See attached.


3. The Attempt at a Solution
I have no idea where to start. I've been banging my head against this problem for 2 hours now. I just don't see how on earth I can find theta with respect to x when it appears nowhere in the given equation! I think I am missing a key concept here. I don't want someone to just do the problem for me, but I need a starting direction.

Thanks!

Hi DanielFaraday! Welcome to PF! :wink:

I'm afraid it takes a long time to get an attachment approved (and a lot of members don't like opening them anyway).

Can you just type out the problem for us? :smile:
 
Wow. You mean to tell me that every single attachment is reviewed before others can view it? That's downright laughable. I hope whoever has that job is getting paid. :rofl: Sorry, but that just doesn't make any sense. It creates a massive bottleneck that slows the entire forum down. What is the "Report" button for if not for reporting inappropriate attachments?

It also stops this foum being banned in schools/colleges/workplaces because someone posted porn, or a virus and it stops people leaving because every second post is an ad for viagra.

No, it only slows you down. :wink:

As I said, if you'd care to take the time to type out your problem, we'll take the time to help. :smile:

Now that the attachment has been approved ...

It looks like a typo. The first equation should be in terms of x and y, not y and z.

The description of each aperture (single slit, or rectangular aperture) is really telling you about the limits of integration.
