Question

What is the size of the image formed by the convex mirror?

Answer 1

Convex mirror

1. A mirror with a reflective surface curved outward is called a convex mirror.
2. A convex mirror is also called diverging mirror as it diverges the light rays.
3. The convex mirror always forms virtual images due to its ability to diverge all the light rays that fall on it.
4. These mirrors are used in streetlights as they diverge light rays over wider areas.
5. Convex mirrors can diverge light beams and create virtual images, so they are commonly used as rear-view mirrors in automobiles.

Image formation

1. Convex mirrors always form images smaller than the size of the object irrespective of the size of the object.
2. The images formed by the convex mirror are always virtual and erect.

An illustrative ray diagram of the convex mirror when the object is placed at a finite distance from the mirror is shown below.
