  1. Question 1

    Q1. In a simple cubic lattice, the distance between (1 1 1) planes is 2 Å. What is the lattice constant?

    • A) 2√3 Å
    • B) 3.46 Å
    • C) 4 Å
    • D) 2 Å

    Answer: 3.46 Å

    Explanation: Using the formula d = a / √(h² + k² + l²), we get a = d * √3 = 2 * √3 = 3.46 Å.
