90 degrees
(That line is the normal to the mirror.)
We measure them on the either side of the mirror and not on the side of the normal to the surface of the mirror because, if the mirror or any reflecting surface is bent, then there will be a difference between the angle of incidence and angle reflection which can be avoided by measuring those angles on the either side of the mirror.
The distance of the object from the mirror line should equal the distance of the image from the mirror line.

Angle of depression is the angle between a horizontal line and the line joining the observer's eye to some object beneath the horizontal line. ^_^
In theory, the answer is "an infinite number". In practice, light will be deflected away from the theoretical by small defects in the mirror and the glass in front of the mirror, as well as absorbed. These will reduce the number of images.
The distance between the image and the plane mirror is the same as the distance between the object and the mirror. Therefore, if the object is 15m away from the mirror, the image will also be 15m behind the mirror.
When a small object is placed on the principal axis of a concave mirror between the focus and the mirror, a virtual and upright image is formed behind the mirror. The image is magnified and located further away from the mirror than the object.
When using a concave mirror, the object distance (distance of the object from the mirror) can vary depending on where the object is placed. If the object is located beyond the focal point of the mirror, the object distance will be positive. If the object is placed between the mirror and the focal point, the object distance will be negative.
The image is equivalent to object in magnitude implying that the image is of the same size as the object.
Yes, the image in a concave mirror can be larger than the object if the object is placed between the focus and the mirror. This creates a virtual, magnified image.
A mirror image is a reflection that appears to be reversed left to right, while an object is a physical entity that exists in space. In a mirror image, the image appears as if you were looking at the object's reflection in a mirror.
When the object is between the center of curvature (C) and the focal point (F) of a concave mirror, it forms a virtual, upright, and magnified image behind the mirror. This configuration is often used in makeup mirrors, shaving mirrors, and headlights to provide a magnified reflection of the object without having to move the mirror closer to the object.
The distance between the object and mirror is 15 mm. The distance between the image and mirror is 15 mm. Therefore, the distance between the image and object is 15 mm plus 15 mm which equals 30 mm.
To generate a real image of an object using a concave mirror, place the object beyond the focal point of the mirror. Light rays from the object will converge after reflecting off the mirror, forming a real and inverted image. Adjust the distance between the object and the mirror to focus the image.
To generate a real image of an object using a concave mirror, place the object farther from the mirror than its focal point. The real image will be formed on the same side of the mirror as the object, and it will be inverted and magnified. Adjust the distance between the object and the mirror to focus the image at the desired location.
A plane mirror forms 1 virtual image and no real image. The virtual image is behind the mirror, at the same distance as the object in front of the mirror, erect, in mirror image left-right.
In a plane mirror, the image distance (di) is equal to the object distance (do). The image formed is virtual, upright, and the same size as the object, and it appears behind the mirror at the same distance as the object in front of the mirror.
