hope this helped! :)
Object distance in mirrors refers to the distance between an object and the mirror's surface. It is the distance at which the object is placed in front of the mirror to be reflected.
The object distance in a mirror affects the size and orientation of the image. The farther the object is from the mirror, the smaller the image will appear. The closer the object is to the mirror, the larger the image will appear. The orientation of the image will also change depending on whether the object is placed in front of a concave or convex mirror.
Object distance is the distance between the object and the mirror, while image distance is the distance between the mirror and the image that is formed. These two distances are related by the mirror equation, which states that the object distance multiplied by the image distance is equal to the focal length of the mirror.
The shape of a mirror, whether it is concave or convex, affects the object distance. In a concave mirror, the object distance can be either positive or negative, depending on the position of the object relative to the focal point. In a convex mirror, the object distance is always positive.
Object distance in mirrors is measured from the center of the mirror's surface to the object. This can be done using a ruler or measuring tape. The unit of measurement used is usually in centimeters or meters.
