X-ray Diffraction and Bragg's Law

[@shelby5725]

thank you! i'm taking biochemistry this semester. you've helped me a lot :)

[@PolymerWorld]

Glad I could help!

[@claycharms8187]

Excellent explanation, thank you very much!

[@rajshekharparmar2041]

Nicely explained video on Bragg's law establishment condition,with proper explanation of path difference and it's influence on x-ray diffraction. Most of the videos on youtube are just accompanied by poor/no explanation👍

[@PolymerWorld]

Thanks for feedback!

[@mateuszcielas3362]

so basically 2 layers are made into one?

[@saipensai4450]

this is very helpful ma'am, thank you!

[@PolymerWorld]

Glad it was helpful!

[@ganeshgaur2002]

Mam can u plz tell me that if we increase or decrease the wavelength of incident beam in comparison to d(interplanar distance)then why does the wave doesnt penetrate in the crystal..I mean to say how does wavelngth actually affect the penetration of wave in crystal?

[@rishabsahoo7154]

It's not the wavelength that is changed, it's the angle that is changed until such an angle is reached that produces a constructive interference of the scattered x-ray waves coming out from subsequent atomic planes. X-rays penetrate through the crystal but the only thing that affects the image is the way they interfere(constructively or destructively)

Please cover the full GATE syllabus of polymer science

[@ishaqktktech4372]

How to constructive interference occur if two rays travel at different paths for constructive interference the rays must be travel at same path??

[@sunmoniborah6589]

Thanks ... ma'am..now I understand completely

[@PolymerWorld]

Glad it was helpful.

[@girijaprasadmandal787]

Awesome explanation 😍😍

[@Trollers233]

What is meant by order of reflection?

[@PolymerWorld]

The order of the reflection (n) corresponds to the path difference between X-rays diffracted from two different layers of crystals. So if extra distance traveled by X-ray is exactly one wavelength, it is a first order reflection, if path difference is equal to two wavelength order of the reflection is second order.

hello
i have an assignment to make on polymer chemistry ,can you give me some pointers and suggestion on how to make it i need some guidance.thank you

[@PolymerWorld]

what is your field of study?

[@saar.a]

great video, thank you

[@asgharali8094]

how I can calculate discharge of polymer from barrel

[@PolymerWorld]

Please check this link for more information on this topic zeus.plmsc.psu.edu/~manias/MatSE447/21_Extrusion2.pdf

[@affankhan2201]

Nicely explained

[@ganeshgaur2002]

I also want to know that when an incident beam strikes on atom then the wave is scattered in all 3D space then how does we sum up all those reflections in one particular direction like u have shown in diagram???? Im waiting for ur reply ...Plz try to reply as soon as possible..

[@kuleshovladimir]

Hello, you have really nice work. Is it possible to send me your presentation?

[@aswathip6060]

So much thankful

[@PolymerWorld]

Thanks for watching!

[@artisidhdhapura3356]

So nicely explained

[@PolymerWorld]

Thank you so much 🙂

[@satyabratadas2767]

Thank you

How can this video be referenced

[@Sivagurudk]

Pls upload al xe f polymer 2008 - 2020 all questions with solutions and explanations. xe c material questions too.

[@PolymerWorld]

2020 GATE XE-F solution coming soon.

[@vinayyadav8638]

Please upload gate 2020 solutions soon

[@PolymerWorld]

We will upload this as soon as possible. We are also working on lecture videos on GATE syllabus. We will let you know once it is uploaded.

[@manishbhakt3822]

Are you from polymer science branch

[@PolymerWorld]

yes, we are doctorate in polymer science

[@jeeonly8190]

Thnx mam....😊
