Question

The symbols [100], {100} and (100) in a crystal represent the sequence

• A. form, line and face
• B. form, face and line
• C. line, face and form
• D. line, form and face

Answer 1

The Correct Option is D

In crystallography: [100] refers to a direction (line), 
{100} refers to a family of planes (form), 
(100) refers to a specific plane (face). 

Thus, the sequence for the symbols [100], {100}, and (100) is line, form, and face, making option (D) the correct choice
