Which of the following properties make the convex mirror useful as a driving mirror? i. the image is real. ii. the image is erect. iii. it has a wide field of view. iv. the image is magnified.
Answer Details
The properties that make a convex mirror useful as a driving mirror are:
- The image formed by the mirror is virtual, meaning it is not real, but appears to be behind the mirror. This is the opposite of a real image, which is formed in front of the mirror. So, statement i is incorrect.
- The image formed by the mirror is erect, meaning it is not inverted. This is important for a driving mirror because it allows the driver to quickly and easily interpret the image without confusion. So, statement ii is correct.
- The mirror has a wide field of view, which means that it can reflect light from a larger area compared to a flat mirror or concave mirror. This allows the driver to see more of the surroundings, making it easier to spot potential hazards. So, statement iii is correct.
- The image formed by a convex mirror is smaller than the object itself. This is the opposite of magnification, which would make the image larger. So, statement iv is incorrect.
Therefore, the correct answer is option ii and iii.
