A virtual erect image of the same size of the object is formed.
Plane Mirror And Other Spherical Mirrors Bulged Outside, Such As Convex Mirrors
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.
A concave lens will appear!

The answer is 15 millimeters behind the mirror, and the distance from the actual object to the image is 30 millimeters. Plane mirrors have a flat focus that places the image as far behind the mirror as you are in front of it.
In case of reflection at a concave mirror as the object is placed at its center of curvature we get the same size And in case of lens, as object is placed at 2F, we get same sized image

Mirror reflects light from an object and that means that it reflects light from the right side of an object to the right side of a mirror and light form the left side of an object to the left side of a mirror. The picture that is created in a mirror is actually a reflection of an object that is in front of a mirror and therefore it looks reverse.
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.
Put a mirror in front of it.
A concave lens will appear!
40cm
It's a virtual reflection of the object which appears as an image as much behind the mirror as the distance of the object in front.
real reflection of the object in front of it at a time.
The same speed: the image will always appear to be at a point exactly behind the mirror as the object is in front.
