A student is looking directly at a lit nightlight through two different cardboard tubes as shown. Through which tube, if any, will the light be seen and why?

• 1. The bent tube only because the light bounces off the sides of the tube and travels through the tube to the student’s eye.

• 1. The straight tube only because the light travels in a straight line directly to the student’s eye.

• 1. Both tubes because light travels equally well along straight and curved paths.

• 1. Neither tube because both tubes absorb all of the light.

Mike conducts an investigation by shining a flashlight toward a flat mirror. He changes the angle of the mirror and observes the path of the reflected light. As the mirror changes direction, the light reaching the mirror can reach the ceiling because the light-

• travels through air and does not change its direction in air

• refracts in the glass of the mirror and is spread out all over the room

• enters the mirror and changes direction when it is refracted by the back of the mirror

• travels in straight lines and reflects from the surface of the mirror
