So for this question we need to draw a unit cell given along with their miller indices mentioned.
00:09
So the miller indices mentioned for first unit cell is orthorhombic.
00:15
Orthorhombic cell with a miller indices of 0 1 1 plane.
00:25
So if you draw a orthorhombic system so an orthorhombic system is like this.
00:37
So for this system we draw a miller indices for 0 1 1 plane then it comprises of this is point number 1 this is point 2 this is point 3 and this is point 4.
00:59
A plane passing through this four point will generate a 1 1 plane.
01:06
The shaded region is a 0 1 1 plane.
01:10
Similarly for b that is a monoclinic unit cell with 1 2 1 miller indices.
01:20
So a monoclinic cell has monoclinic unit cell is like this.
01:39
Similarly a second so this will be generating a cell with 1 2 1 miller indices.
01:58
This 1 2 1 are intercept and reciprocal of an intercept results into miller indices.
02:07
So for 1 2 1 plane it will be like this...
