What are Miller Indices?

Calculate the Miller indices of crystal planes which cut through the crystal axes at (i) (2a, 3b, c) (ii) (a, b, c) (iii) (6a, 3b, 3c) and (iv) (2a, -3b, -3c).

What are indicators ?

A plane is parallel to x & z axes and makes unit intercepts along y-axis. Its Weiss indices are --------. Its Miller indices are --------. The plane is designated as -------.

The Weiss indices of a plane are 1/2, 1/2, 1/2. Its miller indices will be -----and the plane is designated as ---------.
