Question

The Weiss symbol of a crystal face is 4a: 2b: c. The value of h in the corresponding Miller Index (hkl) is

Hint:

To convert a Weiss symbol to Miller indices, take the reciprocals of the intercepts.

Answer 1

Step 1: Understanding the question.
The Weiss symbol (4a: 2b: c) represents the intercepts of a crystal face with the axes of a crystal system. To convert this into a Miller Index (hkl), we take the reciprocals of the intercepts.
Step 2: Analyzing the solution.
The reciprocal of the intercepts is calculated as follows:
For the Weiss symbol 4a: 2b: c, the corresponding Miller Index is (hkl) = 4: 2: 1. This gives the value of h as 4.
Step 3: Conclusion.
The correct answer is 4, as it is the value of h in the corresponding Miller Index.
