Bouncy Bouncy Part 1 (Posted on 2006-02-08) Difficulty: 2 of 5
Part 1: Laser

A laser is fired at a flat mirror.

The laser beam starts at the point (0,5) following the equation y = 5 - x/3 heading down to the right.
The mirror follows the equation y=x/2.

Find the equation for the path the beam takes after it hits the mirror.

Reflect the source point (0,5) about the line y = x/2 to get the point (U,V). The line (U,V)-(6,3) is the path the beam takes after it hits the mirror.
