# Hecht optics: Request for screenshot of this figure please

• e101101
In summary, there was a request for someone to screenshot a figure from a book and send it. The discussion also touched upon copyright laws and the possibility of the OP taking a picture themselves.

Homework Statement
need figure to solve problem.
Relevant Equations
none
Can someone simply screenshot this figure and send to me: Consider Figure 5.4 d) on page 153 of Hecht. As shown, converging rays that are headed toward the point F convert to a plane wave upon hitting the boundary between n2 and n1.

I could. It took me 4 minutes to find it. About 10\$ at my current hourly rate. If you can explain why you want to let me steal this instead of infringing on his copyright yourself, I might be inclined to oblige...

Can't you just a (good quality) picture with your phone and attach that picture as a file in your post?

My phone can only phone ... looks like a nokia 105 but is at least twelve years old.
But thats's not the point.
I was referring to

And the apparent 'passive attitude' of the OP ...

Under "Fair Use" laws for copyrights, a very limited portion of a copyrighted work can be quoted or reproduced for the purpose of commenting on it or asking questions about it. Attribution needs to be included along with a link or citation to the original copyrighted work. As long as the OP includes a link or citation of the book and section with his post of the picture, that should qualify as Fair Use, IMO.
