Q. Magnification produced by a rearview mirror fitted in vehicles is?
Answer: Magnification produced by a rearview mirror fitted in vehicles is less than one.
m < 1.
Magnification is a distortion of the image, meaning it will change your perspective. It alters the size and appearance of objects in relation to their distance from the mirror. In optics, this can be described with a simple formula: magnification = object-image distance / (object-mirror distance).
Rearview mirrors sit close to your face, so you will see greater magnification than if you were using a handheld mirror. But because they are installed onto cars (usually at the base of the windshield), they produce less than one times magnification.
The convex shape of the mirror’s surface also contributes to the distortion. The image appears smaller but taller and wider.
The most common type of rear view mirror is made for a driver of average height in their car. These are installed in positions that reflect what we see without any distortion. A convex mirror installation alters a driver’s view of the world. The object appears slightly smaller than it is, but its height and width are also distorted. The image you see in a car’s rear view mirror is imperfect: the distances between your eye and the object remain the same — only the size changes.
