Question

A ray of light along $x+\sqrt{3}y=\sqrt{3}$ gets reflected upon reaching $x$-axis, the equation of the reflected ray is

• A. $y=x+\sqrt{3}$
• B. $\sqrt{3}y=x-\sqrt{3}$
• C. $y=\sqrt{3}x-\sqrt{3}$
• D. $\sqrt{3}y=x-1$

Answer 1

The correct option is B $\sqrt{3}y=x-\sqrt{3}$


Equation of $A^{\prime }B$
$y+1=\frac{0+1}{\sqrt{3}-0}(x-0)$
$\Rightarrow \sqrt{3}y=x-\sqrt{3}$
