Final answer:
The light from a car behind you reflects off the car, bounces into the rear-view mirror, and then reaches your eyes, in accordance with the law of reflection.
Step-by-step explanation:
When you see a car behind you in the rear-view mirror, the correct path the light takes is described as follows: Light reflects off the car, enters the mirror, and then reaches your eyes. Therefore, the correct answer is B. Light reflects off the car, enters the mirror, and then reaches your eyes. The law of reflection states that light will reflect off surfaces such as mirrors at the same angle at which it arrives, and our eyes then process this reflected light, allowing us to see the image. When you glance in the rear-view mirror, the light is reflecting off the car behind you, then off the rear-view mirror, and subsequently traveling to your eyes, enabling you to perceive the car positioned behind you. This perception is grounded in the characteristics of how light rays behave with mirrors.
