Can u help me to more understand about standing wave?

Now I have one question to ask u: for example, I have the value of Bragg angle and of latice constant: (degré) a (pm) 11,6 665,4 13,5 661,8 19,6 651,3 23,9 660,5 28,4 649,7 and i have the vawe lengh used = 154,5pm. How can we calculat the Miller index? Thank for the response to me.

if i have: (degré) a (pm) 11,6 665,4 13,5 661,8 19,6 651,3 23,9 660,5 28,4 649,7 and wave lengh = 154,5pm . How we can calculat the Miller index? Thak for the friend who will want give me the respons.

yes i understand here, but how to obtain: {220} = (220),(202),(022),(-220),(2-20),(-202),(20-2),(-2-20),(-20-2),(-20-2) etc.?with the calculat?

Ok i agree with u about this, but for exemple, the value of {h^2+k^2+l^2} is equal to 8 so we will get the Miller index for example: h=2; k=2 and l=0 or we write (220). if we want get (202) or (022) , are there possible? Thank for your response.

So we can not calculate directly all this index? In Bragg relation, if we know the angle incident, so we can calculat the distance inter_reticular, suppose that we know about wave lenght.From heer, do we can calculate the Miller index? if yes , how to do? Thank for respons.

Yes i know about this, but i want ask u: what is the different between (102) et (012)? how to obtain(102) ?are there the methode to take this?Thank.

How we can calculate the Miller's index? :smile: Thanks
