TEST BANK FOR Introduction to Solid State Physics

Exam (elaborations) TEST BANK FOR Introduction to Solid State Physics The vectors xˆ ˆ + + y zˆ and − −xˆ yˆ + zˆ are in the directions of two body diagonals of a cube. If θ is the angle between them, their scalar product gives cos θ = –1/3, whence . 1 cos 1/ 3 90 19 28' 109 28' − θ = = ° + ° = ° 2. The plane (100) is normal to the x axis. It intercepts the a' axis at and the c' axis at ; therefore the indices referred to the primitive axes are (101). Similarly,...
