Question

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

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

Answer 1

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

$\begin{array}{c}y+1=\frac{1}{\sqrt{3}}\left(x-0\right)\\ \sqrt{3}y+\sqrt{3}=x\\ \sqrt{3y}=x-\sqrt{3}\end{array}$

Hence,

Option $B$ is correct answer.
