Final answer:
Amy is correct. The flashlight on the other side of the mirror apparently moves from point D to point C.
Step-by-step explanation:
According to the information provided, Amy is holding a flashlight at point A and Taylor, at point B, sees a reflection of the flashlight on the other side of the mirror. Amy turns off the flashlight at the same time as Carl, at point C, turns on another flashlight. Amy claims that Taylor must see the flashlight on the other side of the mirror apparently move from point D to point C. Is she correct?
Based on the principle of reflection, the direction of the reflected light is determined by the angle of incidence. When Amy turns off her flashlight at point A, the light ray stops reflecting off the mirror at point D. At the same time, Carl turns on his flashlight at point C, causing a new light ray to reflect off the mirror at point C. Therefore, Taylor would indeed see a change in the location of the reflected light from D to C as a result of Amy and Carl's actions.
In conclusion, Amy is correct in stating that Taylor would observe the flashlight on the other side of the mirror apparently move from point D to point C.
