1. What reqiurements does a quadrangle need that all the perpendicular bisectors of the sides crosses in one point??
2. And how can you proof it?
To 1. - I think each angle have to be 90° but I can't proof it :blushing:
I am not sure if I understand this... If we've got an atom like H and we firing x-ray at it, does it then oscillate (like a dipole) and scatters the x-ray into another direction? And in WHAT direction?
Am I totally wrong with that? ;)
Hello!
This time I've got a question about the "Rayleigh-scattering" in X-Rays.
The Rayleigh-scattering says, that the x-ray changes it direction only without "loosing" energy.
Why does this happen and what has it to do with dipoles? My university professor told me, that the...
It's me again :smile:
I've got another question to the x-rays:
Why do we see something on a screen or an a picture or ... if the doctor x-rays e.g. my hand? Is there a more scientific answer than that the x-ray gets absorbed by my bones and there the picture stays white?
Thanks for your...
wow, thank you very much for so many replies!
know I've got enough to read ;)
some more questions I've got, which need to be explained in a very easy way:
- How can you "create" x-rays?
- and what can you do with it...
it would be great if i get as much replies as yesterday :)
thanks a...
Hey!
Of course you can help me! :) I need some information about HOW TO MAKE X-RAY VISIBLE. I know that it depends on the atomic number, but I need it more specific, do you know where I can get some information about my problem?
I don't want you to write an essay for me, but I really need some...
