What is a characteristic of convex mirrors commonly found on buses?

Convex mirrors are designed to provide a wider field of view compared to flat or concave mirrors. This is particularly advantageous in settings such as buses, where the driver needs to monitor the area behind and around the vehicle for safety reasons.

One of the primary characteristics of convex mirrors is that they cause reflections to appear smaller and farther away than they really are. This wider perspective allows drivers to see more of their surroundings, making it easier to spot pedestrians, cyclists, and other vehicles that may not be directly behind them. Hence, this feature of making objects appear smaller is crucial for ensuring that drivers can manage their vehicles safely in crowded environments.

The other choices relate to how images are distorted in various mirror types but do not accurately describe the functionality or characteristics of convex mirrors. The focus on the reduced size and apparent distance underscores the utility of convex mirrors in maximizing visibility while driving.
