A convex mirror is a type of spherical mirror that bulges outward like the back of a spoon. It has a reflective surface on the outside and a hollow curved shape on the inside.
A convex mirror produces a virtual image by reflecting light rays divergently. This means that the reflected light rays appear to come from a point behind the mirror, creating an image that appears smaller and upright.
The main difference between a convex and a concave mirror is their shape. A convex mirror bulges outward, while a concave mirror curves inward. This results in different properties, such as the convex mirror producing only virtual images while a concave mirror can produce both real and virtual images.
The size of an object affects its image in a convex mirror by making the image appear smaller than the object. This is because the light rays are diverged by the convex mirror, causing the image to appear further away and smaller than the object.
Convex mirrors have a wide range of practical applications. They are commonly used in security cameras, rear-view mirrors in cars, and in store security to provide a wider field of view. They are also used in traffic mirrors to eliminate blind spots and improve safety on roads.
