A ray of light coming from the point ( $\displaystyle 2,2 \sqrt{3}$ ) is incident at an angle $\displaystyle 30$° on the line $\displaystyle x=1$ at the point A. The ray gets reflected on the line $\displaystyle x=1$ and meets $\displaystyle x$-axis at the point B . Then, the line AB passes through the point :
