Solved Problems on Bragg's Law 

A X-ray of wavelength λ when incident on the (101) plane of a cubic lattice with lattice constant a produces first order Bragg's reflection at 0=30° (grazing angle). Suppose that lettice is compressed along the 3-axis so that lattice parameters along the x and y axes remain the same while the along the 3-axis become a/(sqrt(3)) * The first order reflection for the (101) plane of the compressed lattice occurs at- A. 30 degree B. 15 degree C. 45 degree D 60 degree

So when h²+k²+l² is 2 what will be the milner index

Great explanation

In the x-ray diffraction for tantalum powder, the following angles were obtained using radiation of wave Length 0.15406nm 19.6,28.1,35.1,41.5,47.7,54.1,54.1,60.8,68.9. Find, I,)the corresponding lattice planes. ii)the lattice type. ii) lattice parameters. Plz help me mum, am grateful for your lecture.

❤❤❤❤

Very helpful mam for preparing enterances. Thank you so much. 😀

Thank you mam, well explained

Thank you sooo much ma'am❤❤👍 Very helpful video

Really its nice explanation

Miss In the second question it says in the question 2nd order but you take n as 1. Why?

Calculate the Bragg angle if (111) planes of a cube (a = 3.57 A) crystal are exposed to X-rays (wavelength - 1.54 Å). Plz reply ma'am

Very helpful

How did you find lattice parameter using the formula for Simple cube but here we have to deal with FCC

Your handwriting 🙇🏻‍♀️🙇🏻‍♀️

questions are good mam🙂thank you

Very clear mam.thank you very much❤❤

Thank you so much mam

Thank you 😊 so much Mam

Thanks mam Ur videos are very helpful

Mam can u please make the videos of quantum mechanics in details

Nice

very clear thx u

Thnq ma'am ❤️

😊😊😊

Thanks mam👍☺️

Maam are you from kerala?

Na = 6.023 * 10^23 you took 10^26

Too long

How this calculations.. 🥲🥲
