Final answer:
The use of diverging or convex mirrors in vehicles allows for a wider field of view, but distorts distance perception, making objects appear further away than they are.
Step-by-step explanation:
You should use your mirrors to check where the rear of your vehicle is while you make turns. Mirrors, specifically rear-view mirrors, are essential tools for drivers. Diverging mirrors, also known as convex mirrors, are often used for rear-view mirrors in vehicles because they provide a wider field of view than flat mirrors, allowing drivers to see more of the area behind them. However, the main disadvantage of using a diverging mirror compared to a flat mirror is that objects appear smaller and therefore at greater distances than they actually are, which can potentially lead to misjudgment of distances and the speed of approaching vehicles.
