A ray of light along x +underroot( 3) y =underroot(

3 )gets reflected upon reaching x-axis, the equation of the reflected ray is?

please explain?

eqn of reflected ray will be uderroot(3)y = x - underroot(3) take x axis as mirror and thus y intercept of reflected ray will be -1 and slope will be opp of the slope of incident ray...i.e. if the slope of incdnt ray is negative then slope of rflctd ray will be positive and the magnitude remains same....thus by slope-inercept form you can easily write the eqn of reflected ray.....
