Question 1 of 5

A two-dimensional lattice has basis vectors $\vec{a}=2 \hat{i} \ { and \ } \vec{b}=\hat{i}+\hat{j}$ . Find the corresponding reciprocal lattice vectors.

A

$\frac{\hat{i}+\hat{j}}{2} \operatorname{and}\ 2 \hat{j}$

B

$\frac{\hat{i}-\hat{j}}{2} \ { and\ } 2 \hat{j}$

C

$\frac{\hat{i}-\hat{j}}{2} \ { and\ } \hat{j}$

D

$\frac{\hat{i}+\hat{j}}{2} \ { and \ } \hat{j}$
