Weiss Zone Law & vector/planes

1. The problem statement, all variables and given/known data

Use the Weiss Zone Law to determine a vector which lies along the line of intersection of the (221) and (122) planes.

2. Relevant equations

hU+kV+lW=0

3. The attempt at a solution

hU+kV+lW=0
2U+2V+1W=0 eqn(1) 1U+1V+2W=0 eqn(2)
1W=(-2U-2V)

Sub into eqn (2)

1U+1V+2(-2U-2v)=0
1U+V-4U-4V=0
-3U-3V=0
3U+3V=0
U=-V

1U+1V+2w=0 eqn(2)
-V+1V+2W=0
2W=0
W=0V

V=V
