Name the following crystallographic features below using proper crystallographic notation.
Image One
[2ˉ21]
[1ˉ12ˉ]
[1ˉ1(1/2)]
[(1/2)(1/2ˉ)1ˉ]
Image 2
(1ˉ02)
(21ˉ0)
(201)
(1ˉ02ˉ)
Image one (d)
Image two (a)
I hope this helps. :)
Thanks for the help but it Wasn't right!
Tried with Image One:[(1/2)(1/2ˉ)1ˉ] Image 2:(1ˉ02) but got it wrong! any idea what it is!
Image 1: b
Image 2: ?
Image 1: b
Image 2: c
Thank you!
Got it and Thank you everyone!
Its not right
i didn't get it either
To name crystallographic features using proper crystallographic notation, we use a combination of integers and symbols to represent the orientation of the crystal planes and the direction of crystallographic axes. The notation consists of square brackets "[" and "]" for planes and parentheses "(" and ")" for directions, followed by the Miller indices in the form (hkl).
Image One:
1. [2ˉ21]: This notation represents the crystallographic plane normal to the [2ˉ21] direction.
2. [1ˉ12ˉ]: This notation represents the crystallographic plane normal to the [1ˉ12ˉ] direction.
3. [1ˉ1(1/2)]: This notation represents the crystallographic plane normal to the [1ˉ1(1/2)] direction.
4. [(1/2)(1/2ˉ)1ˉ]: This notation represents the crystallographic plane normal to the [(1/2)(1/2ˉ)1ˉ] direction.
Image 2:
1. (1ˉ02): This notation represents the direction [1ˉ02] in crystallographic notation.
2. (21ˉ0): This notation represents the direction [21ˉ0] in crystallographic notation.
3. (201): This notation represents the direction [201] in crystallographic notation.
4. (1ˉ02ˉ): This notation represents the direction [1ˉ02ˉ] in crystallographic notation.
In crystallography, the integers within the brackets and parentheses are the Miller indices, which represent the intersection of the crystal planes or crystallographic directions with the axes of a crystal lattice. The negative sign (ˉ) above a number indicates the direction opposite to the given axis, while fractions within parentheses represent axes not parallel to any specific lattice axis.
To obtain these Miller indices, you need to use certain crystallographic techniques like X-ray diffraction or electron diffraction. These techniques involve measuring the angles and intensities of the diffracted X-rays or electrons, which can then be used to calculate the Miller indices and determine the crystallographic features.
