F A Here, we're looking down on a room with 6 people. The bottom wall (including point X) and the left wall are mirrored. Person F fires a laser beam at point X. Who gets hit by the laser? In your answer below, include your reasoning and reflected angles for full credit. If more than one person is in the possible path, indicate that as well (the first person might duck out of the way!).

Q.7 A retroreflector is any optic that reflects an incident ray, such that the exiting ray is parallel (but opposite) to the incoming ray. One version of a "cat's eye" retroreflector uses a thin positive lens of focal length fand a flat mirror as shown below. (a) Determine the matrix of retroreflector shown in Fig. Q7. (b) Use the matrix method to prove that it is, indeed, a retroreflector. Fig. Q7

A parallel beam of light is incident on a convex mirror parallel to the principal axis. Which statement below best describes the reflected beam of light? O Itis also parallel to the principal axis. O It appears to come from the center of curvature of the mirror. O It converges to a point on the principal axis back from the mirror, O It appears to be coming from the focal point behind the mirror.

ASK YOUR TEACHER As shown below, light from a vacuum is incident on a shard of Shawtonium (a newly discovered compound). The backside of the shard is up against an unknown material. When the light strikes the backside of the shard, total internal reflection occurs. The light then emerges from the side of the shard and resumes traveling through a vacuum. The index of refraction of Shawtonium is 1.6. Determine e, & 02. vacuum 0, = shard 02 = 02 770 unknown 39°
