Question

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

Accepted Answer

Equation of reflected Ray P'B :

y - 2$$\sqrt 3 $$ = tan 120o (x - 0)

$$ \Rightarrow $$ $$\sqrt 3 $$x + y = 2$$\sqrt 3 $$

(3, -$$\sqrt 3 $$) satisfy the line.
