Unformatted text preview: 4. Miller indices of a plane and a direction normal to that plane in cubic system are a. large b. same c. different ( b ) 5. The direction along which atoms touch each other in face centered cubic crystal is a. along cube edge b. along the face diagonal c. along the body diagonal ( b ) 6. Bonus: That h+k+l should be even to observe a peak in X-ray diffraction pattern of a bcc crystal is a result of a. constructive interference of the X-rays reflected from different planes b. the amplitude of the X-rays scattered by different atoms in the unit cell is not zero c. the material not to be amorphous ( b )...
