Calculation of the a-to-r ratio for diamond cubic

In this video Parisa works through the calculation of the a-to-r ratio for the diamond cubic crystal structure.

This, in combination with your first video on the diamond crystal structure really help to understand it.
Everything was explained so nicely. Thank you to both of you and your team.

woooow such a beautiful guider..she is alike indian actress tapsi panu....

I can't concentrate online classes and came here and now had full concentration...

[TonTon-ujgm]

Thanks for that two triangles method, my prof never told me that...

[윤규원-iu]

Just focus on the lecture, not lecturer boys.

Beauty with brains ! Love you jaaneman

How can you be sure that it's a/4 along/in/up?

[rajatkatiyar]

U really explain very short trick thanks a lot

[보리-spk]

woooow. It helped me a lot. Thank you.

You can also just find the distance from the center of one atom to the other in terms of r and a to get 2r = sqrt(3*(a/4)^2). Where I just used the distance formula with x=y=z = a/4 to get the distance in terms of a.

please let me know how the second triangle she shown is 90 degree from edge it should be 90 degree from plane right ????

[AzeraKotaro]

what the difference between this diamond cubic and fcc ?

[sjjshshhshsj]

use body diagonal each carbon center cuts at 4 equal parts use this the above method is bit complicated

[Virtualexist]

If not for beauty but I am not happy for the missing explanation of quarter way over there. where ? how ?

[afakethrum]

Sorry but "quarter way point is over here" does not explain anything.

[ramithan]

Top Viedo, helps me alot. Thank you :D

[syediqramulhoque]

"quarter way point is over here" it should have been explained

[basharatahmed]

U r looking beautiful....I m confused should i focus on your lecture or on you....

[abdelrahmangamalmahdy]

is an amazing girl :) plz let her make more videos

[shahejadsayyad]
