The equation describing the shape of curved mirror with the property that the light from a point source at the origin will be reflected in a beam of rays parallel to the x-axis is (with Q1. a as some constant) (a) y = ax +a (6) 2y = x +a (c)y=2ax+a (d)y= ar +2a
Paraboloid is a shape you obtain when you rotate the parabola on its symmetric axis.
The parabolic mirror is used in automobile headlights , solar concentrator , dish antennas , r...
