The image formed by a convex mirror is always virtual, meaning that it cannot be projected onto a screen. This is because the reflected rays do not actually converge to a point. Instead, they appear to diverge from a virtual image point behind the mirror.


The image formed by a convex mirror is always smaller than the object. This is because the reflected rays spread out as they reflect off the mirror, resulting in a decreased size of the image.


The image formed by a convex mirror is always upright, meaning that it has the same orientation as the object. This is because the reflected rays do not cross over each other, as they do with a concave mirror or lens.


The image formed by a convex mirror is always located behind the mirror, between the mirror and the virtual image point. The distance of the image from the mirror depends on the distance of the object from the mirror and the focal length of the mirror.

In the given scenario, the object is placed at a distance of 30 cm in front of a convex mirror of focal length 15 cm. The image formed will be:
- Virtual
- Smaller in size than the object
- Upright
- Located behind the mirror, between the mirror and the virtual image point.

The exact location and size of the image can be determined using the mirror formula:
1/f = 1/v + 1/u
where f is the focal length of the mirror, u is the distance of the object from the mirror, and v is the distance of the image from the mirror.
