Practice question

Convex curved mirrors are beneficial because they:

  1. Provide a clearer image than flat mirrors
  2. Show a wider area than flat mirrors
  3. Reduce glare from headlights
  4. Eliminate blind spots completely

Answer: B — Show a wider area than flat mirrors

Convex curved mirrors are beneficial because they show a wider area than flat mirrors. Unlike flat mirrors, which reflect light in a straight line and provide a limited field of view, convex mirrors are designed to diverge light rays and create a wider field of vision. This characteristic makes them particularly useful for applications such as vehicle side mirrors, where they help drivers see more of the area next to and behind their vehicle, thereby enhancing safety by reducing blind spots. The ability of convex mirrors to capture a broader view is achieved at the cost of image clarity, as objects appear smaller and more distorted compared to how they would look in a flat mirror. Therefore, while they do not provide a clearer image than flat mirrors or eliminate blind spots completely, their effectiveness in showing a wider area is what makes them valuable for safer driving and navigation in tight spaces.
