Question

Within a cubic unit cell, sketch the directions of [012], [721], [110].

Answer 1

Answer:

[012]  :

Here x component is zero. That is why this is  in y- z plane

[721] :      

This is  in  all three plane .It means it is in space.

[110]  :

Here z component is zero.

That is why this is  in x -y plane

From the cubic unit directions we can easily understand all given directions  [012], [721], [110].
