Question

A ray of light along $straight x space plus square root of 3 straight y end root space equals space square root of 3$ get reflected upon reaching X -axis, the equation of the reflected ray is

$straight y equals space straight x plus square root of 3$
$square root of 3 straight y end root space equals space straight x minus square root of 3$
$straight y space equals space square root of 3 straight x end root minus square root of 3$
$square root of 3 straight y end root space equals space straight x minus 1$

Solution

square root of 3 straight y end root space equals space straight x minus square root of 3

Given equation of line
$WiredFaculty$
Slope of incident ray is $space minus fraction numerator 1 over denominator square root of 3 end fraction$
So, slope of reflected ray must be $fraction numerator 1 over denominator square root of 3 end fraction$ and the point of incident $left parenthesis square root of 3 comma 0 right parenthesis$
So equation of reflected ray
