Question

A coplanar beam of light emerging from a point source has the equation lambdax - y + 2(1+lambda) = 0,lambdabelongs toR,
the rays of the beam strike an elliptical surface and get reflected. The reflected rays form another
convergent beam having equation mewx - y + 2(1 - mew) = 0,mew belongs toR Further it is found that the foot of the
perpendicular from the point (2, 2) upon any tangent to the ellipse lies on the circle
x² + y² – 4y - 5=0.
