Answer:
Miller Indices are [2, 4, 3]
Solution:
As per the question:
Lattice Constant, C = 
Intercepts along the three axes:



Now,
Miller Indices gives the vector representation of the atomic plane orientation in the lattice and are found by taking the reciprocal of the intercepts.
Now, for the Miller Indices along the three axes:
a = 
b = 
c = 
To find the Miller indices, we divide a, b and c by reciprocal of lattice constant 'C' respectively:
a' = 
b' = 
c' =

Answer:
the speed at which something moves in a particular direction
Explanation:
The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. ... Velocity is a physical vector quantity; both magnitude and direction are needed to define it.
