Question

Draw the ray diagram for convex mirror producing real image.

Accepted Answer

A real image occurs where rays converge, whereas virtual image occurs when rays diverge and only appear to come from a point. The real images cannot be produced by a convex mirror as it diverges the rays.

The real image is formed as a result of the actual convergence of the reflected light rays. It can be received on a screen, and it is always inverted

Convex mirror is a curved mirror for which the reflective surface bulges out towards the light source. Convex mirrors reflect light outwards (diverging light rays) and therefore they are not used to focus light. The image is virtual, erect and smaller in size than the object, but gets larger (maximum up to the size of the object) as the object comes towards the mirror. Such mirrors are also called diverging mirrors.

Image Formation by Convex Mirror An image which is formed by a convex mirror is always erect and virtual, whatever be the point of the object. Here, let us look at the types of images formed by a convex mirror.

When an object is pointed at infinity, a virtual image is formed at the focus. The size of the image is much smaller than compared to that of the object.

When an object is placed at a finite distance from the mirror, a virtual image is formed between the pole and focus of the convex mirror. The size of the image is smaller than compared to that of the object.
