Solution

## Convex mirrorAs we all know, a convex mirror's image is always smaller than the object's size, resulting in an erect and fictitious image of the thing. A diverging mirror is another name for it. It is also utilized as a rear view mirror in vehicles because it covers a large area behind the mirror. Demonstrating with the help of a diagramA full-length image of a distant tall building using a convex mirrorA ray of light $AD$ running parallel to the major axis is reflected along with $DX$ when a tall building $AB$ is at a distance from the mirror. When $DX$ is traced backwards, it appears to come from $F$. Another ray, $AE$, is reflected back along with $EA$ as it travels towards the centre of curvature ($C$). When created backwards, these two diverging rays $DX$ and $EA$ appear to cross at $A\text{'}$. As a result, the image of the building generated is imaginary, upright, decreased and behind the mirror. Using a convex mirror, the full-length image of the distant tall building may be clearly viewed.Hence, a full-length image of a distant tall building can definitely be seen by using a convex mirror.
