Question

In edge dislocation, the burger's vector is ________ to the dislocation line

• A. Parallel
• B. At an angle of $45^{\circ}$
• C. Perpendicular
• D. At an angle of $75^{\circ}$

Hint:

Edge = Perpendicular; Screw = Parallel. It is the fundamental way to distinguish between these two types of dislocations.

Answer 1

The Correct Option is C

Step 1: Concept Dislocations are linear defects in crystal lattices defined by the relationship between the dislocation line and the Burger's vector ($b$).

Step 2: Meaning The Burger's vector represents the magnitude and direction of the lattice distortion.

Step 3: Analysis An edge dislocation is formed by inserting an extra half-plane of atoms.

Step 4: Conclusion In this specific geometry, the Burger's vector is always perpendicular to the dislocation line. Final Answer: (C)
