If incident ray from point (-2,4) parall...

If incident ray from point (-2,4) parallel to the axis of the parabola `y^(2)=4x` strikes the parabola, then find the equation of the reflected ray.

Text Solution

Verified by Experts

The correct Answer is:
4x-3y-4=0
Ray parallel to x-axis from point P(-2,4) strikes the parabola at Q(4,4).

So, incident ray SQ passes through the focus.
Equation of SQ is
`y-4=(4)/(3)(x-4)`
`or" "4x-3y-4=0`
