X-Ray Diffraction and Bragg Equation

[@MortezaVafadar]

I love the way you pronounce the words, very clear and explicit explanation. Very useful for foreign students. Thank you.

[@AKLECTURES]

Exactly my intention! glad to hear that! thanks! :)

[@TheSINGARR]

Awesome! Though it's duration is less than 7 minutes, you have given a lot of information which is clearly understood. You saved my time!

[@AKLECTURES]

SpandanaV Great ! :-)

[@johnweldon1259]

Best teacher by far.

[@genemaker4976]

I needed this for geology and it really helped. Clear, concise, accurate. I can't ask for more. Thanks.

[@AKLECTURES]

You're welcome Melanie! :-) Geology is a great subject!

[@pratyushkumardash4410]

I am studying this relating to crystallography under geology...

[@andrewurbanowicz5010]

Thank you so much for you excellent explanations and teaching! I enjoyed this video along with many others. You have helped to make my modern physics class easier! God bless! -Andrew

[@Elias.04]

4:45 I think you meant it travels dsin(theta) more

[@deepthireddyvasi2075]

in one single locution, supreme video .many thanks sir.

[@mangaworm8138]

lol...finally..finally..i understand the concepts...thanx..

[@AKLECTURES]

Manga worm awesome :) you're welcome :)

[@officersmiles9114]

Beautiful video. Thank you so much.

[@rigzenangmo9732]

Tomorrow is my finals and I got the concept just today... thank you so much! loved the way you explained !!!

[@fatinzalila2483]

i wish you can make further explanation bout XRD; phase identification, xrd patterns, diffractometer etc. i like how you explain it repeatedly. you such a good lecturer! awesome

[@Rohit-tz6gs]

Wow, it was an outstanding video. It has cleared all my doubts. I have been watching many lectures since morning on youtube and now, I have got a perfect one.

[@daminisingh3694]

Mind blowing ,,,, explanation ,,,,, thanks a lot sir 😇😇

[@kovoproxy]

thank you, lots of love from central Europe

[@kanav1998]

Here is something you should know.... YOU ARE GREAT .... Fantastic explanations....no one does it better!!😊😄

[@Hero101010]

Thank you very much for sharing, I was having trouble understanding this and you put it across very well!

[@AKLECTURES]

You're welcome!

[@pianomathfreak6178]

Thanks man. You increased my understanding on Bragg's Law

[@abktv1054]

Thanks man

[@ismailalhassan1381]

Am now beginning to understand what xray diffraction is all about. Thanks alot Sir.

[@alfredwhittingdale9192]

4:39 -- 4:44 "And that lower wave will travel a distance of d sin theta less." You mean MORE, not less.

[@Doraemon-gc2lu]

Rght

[@sathishshastry461]

super.and clear explanation ... started loving your lecture..

[@AKLECTURES]

sathish shastry Thank you! :)

[@jacklong646]

I have a naive questions that I hope you can help me with. For waves 1 and 2 in the Bragg diffraction diagram, how can they interfere if they are not even reaching the same position in space? 2. Why do we only consider

[@shivamtrivedi0106]

U explained so well man ! Thanks

[@jaydeepsharma6914]

So prepared and very engaging. GREAT

[@vittopado97]

Great video, I finally understand Bragg equation!

[@nirupomarabha703]

Thanks sir

Fellow Brooklynite here! Thanks for the video :)

[@AKLECTURES]

+Anne Li Yes!!! :-) Did you to go school HS in Brooklyn?

[@pumpvidsmusic]

Yes! I went to Edward R. Murrow :) Now I'm at Johns Hopkins. Did you also go to high school in Brooklyn? :)

[@AbdulHakim-vj3dm]

its very helpful lecture and explanation...I can understand it even just via the first explanation..credit to the lecturer..

[@AKLECTURES]

Abdul Hakim Md Yusop Glad to hear that! :)

[@zacharymundwiller2503]

Absolutely fantastic video.

[@sreenathm7985]

very clear explanation , I really understood the basis of wavelength determination of X ray by diffraction method

[@MegaXwillx]

Awesome! way better than how my professor explains it

[@mehdi9431]

Thank you, your videos are very useful and easy to be understood

[@ashishmishra-qm4ez]

lecture is well structured ..great explanation...

[@palakshappadh8787]

Its so help full to understand distance students

[@AKLECTURES]

Good! :)

[@uriahfingerhut1408]

dude you are awsome!! pls keep do that, it is soooo helpful!

[@frankreiserm.s.8039]

I like this guy! You can build your own x ray machine. Build a Tesla coil from a kit and hook it up to the cathode of a dental x ray tube. Under a photographer's red light, cut a piece of film and hold a chicken leg in between the paper and tube for 20 minutes. You will get an x ray showing the bones.

[@amnaibrahim3705]

good finally i understood

[@kawtharmohammed8495]

This video helped me so much with my project! Thank you :)

[@sunilkamboj4476]

God gifted talent.

[@leothewarrior1]

Good explanation. Thanks

[@sunilkamboj4476]

Very clear explanation , thanks alot.

[@ahmedsalafap5898]

waw, this is cool . You have connected the celebrated 'double slit experiment' with X-Ray diffraction.Thats look more logical. Thank you

[@stankoaksentijevic84]

You are so logical, thank you very much

[@sebastianamado7758]

Muy buena explicación !!! gracias saludos desde Argentina !!

[@shubhamhorambe7903]

Awesome lecture as always..nothing less

[@syedmowla]

Love these lectures :D

[@chanakyasinha8046]

Omg mind blowing teaching 😍😍 thanks, you helped me alot

[@jennazhang4927]

Awesome explanation!!! Thanks!

[@basmaeidarous16]

amazing explanation

[@roseb2105]

I dont understand the part about constructive interference" when the distance they travel is a number multiple of there wavelengthes"??

[@zakariakhan1630]

wonderful very helpful

[@emilydikinsin8137]

Amazing sir your pronouncuation accent is very helpful thank you sir

[@saad3677]

Excellent explaination! Articulate

[@blesskale4267]

OOOO MG...u are too good i even sometimes look for a maths topic u may have lectured on...Why don't u try that too?

[@rabindrakhatiwada3558]

hey man could you make a video on solving phase problems in x rays crystallography

[@alirezasadeghifar3815]

Great job man! Do you have anything about IR Spectroscopy and Neutron Diffraction?

[@theshortcut101]

Extremely good! Thank you

[@AKLECTURES]

theshortcut101 You're welcome! Glad you thought so :)

[@Jarrod_C]

Some molecules are not bonded in a crystal orientation or bonded differently like ionic bonding covalent, etc. Does X-ray crystallography have limits on the types of molecules or compounds it can determine? You should have mentioned briefly its limitations like you mentioned its uses.

[@Quantumphysicst99]

sir what differences between crystal diffraction and x ray diffraction ....?

[@ptilongmarchimrankhan3678]

you are really great Sir!!!!

[@carloszuna110]

Thank you this video was very helpful!!!

[@sarbjyotsinghchahal3361]

great explanation thanks

[@vitoriatonini]

Thank you, great explanation.

[@AKLECTURES]

Glad to hear it, you're welcome!

[@Nanba91]

Great. thank you very much

[@gopalgotmare5379]

Nice keep it up good explanation

[@mohammadrabibhossain687]

thanks for the explanation!!

[@anshulahuja820]

thanks i have an doubt that you told that d is equal to the wavelenght of the x ray so in bragg equation wavelenght cancels out the d and we will get only n= sin of angle

[@evanfolk1170]

he didn't say that d is equal to the wavelength, he said it is on the same order of magnitude. There's a distinction between the two.

[@pnsakanjankumar]

Very good explanation. Really liked it thank you :)

[@AKLECTURES]

Anjan Kumar You're welcome! :)

[@emanaref7296]

thank u that was really helpful !

[@massimiliano93.]

thanks

[@youcefdjedi5563]

hi! what kind of reciprocal lattice dose an isotropic polycrystal have?

[@yinfengjiao8138]

Quite useful, thank you so much!!!!!!

[@urty4395]

Wow man..just wow..

[@arneetkaur1001]

why it is assumed here that diffracted rays appear to be one li ke reflected from crystal planes?

[@sayantanbhowmik4196]

Nice thank you

[@Quantumphysicst99]

and sir i request sir plz send me this lecturer notes this lectures is very understanding and helpful

[@The01danger]

good in explanation

[@dariesparza93]

Reading out of the modern physics book was a little non English, wonderful description.

[@AKLECTURES]

lol! i know that exact feeling! :-)

[@ahmadbagheri3660]

thanks,master

[@muhammadbilal7286]

x-rays are diffracted then reflected...and the reflected waves then interfere...

[@nazishhussain2571]

If the rays of x ray are parallel, they are never going to meet at a point so how come interference takes place? Please clear my confusiom

[@nanokhan6404]

Amazing

[@mekky3765]

I was hoping you would explain miller indices, I came here to know how to read XRD spectra

[@ahmedhass146]

Wow cool man i will follow you man but i have a question what does ( in - phase ) mean ?

[@jthomson9376]

Thank you so much!

[@menot5039]

i love you bro.

[@gowtham5168]

Wonderful ....

[@gurkamal96]

thank you. this was really helpful :)

[@AKLECTURES]

Awesome! You're welcome!

[@noorkhan-ez8xb]

nice sir .

[@bushrakhan5475]

sir when xray fall on fill distructively then in that case what will be expression for braggs law

[@bushrakhan5475]

not fill its film

[@sxarfce]

Thanku

[@marknkh7]

goo ahead. excellent explanation. thank you

[@AKLECTURES]

marknkh7 thank you!

[@kaushikghatak4918]

Mind blowing

[@diviknigam]

Where is the diffraction in the Bragg's experiment - doesn't it just reflect? You didn't say that the x-rays diffract at any point :O.

[@yojam93]

Great video. I have a somewhat of a complex question. I'm being asked to find the length of a cubic structure and i'm given the "d spacing" information (8 total values). Also i'm given that it's molecular weight. I know that this concept applies but i'm not really sure what my instructor means by length. Any insight would be great, thanks!

[@123amouri]

First time that I see youtube's autogenerated english subtitles work haha

[@meruyertryskulbek5558]

Thank you ssoooooooooooooooooooooo much!

[@huutiainen9393]

thank you! i still feel like i dont however understand why its 2dsin(angle) and not just dsin(angle) :(

[@rai-ul-ainkhalid6354]

Huu Tiainen its because the ray first covers distance dsintheta to reach to the atom in the lower surface then it is reflected and again covers a distance dsintheta to reach to the upper surface/boundary.since

[@lylepressley3751]

I had my volume on 1 and you still blew my speakers... Good teaching, though.
