Infinite.
A virtual erect image of the same size of the object is formed.
45 degrees.
A concave lens will appear!
If 2 mirrors are placed perpendicular to each other then infinite no of images will be formed because image formed by one mirror will act as the object for the other and vice verse.
When an object is placed at the focal point of a concave mirror, no real image is formed. This is because the reflected rays are diverging and do not converge to form a real image. Instead, a virtual image is formed behind the mirror, which cannot be projected onto a screen.

When an object is placed within one focal length from a lens, the image formed is virtual, upright, and magnified. This happens because the rays of light are diverging after passing through the lens.
A convex lens will behave as a diverging lens when an object is placed closer to the lens than its focal length. In this case, the light rays will diverge instead of converging, leading to a virtual image formed on the same side as the object.
A diverging lens can produce several types of images, depending on the location of the object relative to the lens. Typically, a diverging lens will produce a virtual, upright, and reduced image for objects placed beyond the lens' focal point.
The image formed by a convex mirror when an object is placed in front of it is virtual, upright, and smaller in size than the object.
A virtual image is formed when diverging rays appear to converge at a point behind the mirror or lens. If the rays do not actually converge, a virtual image cannot be formed. This can happen with concave mirrors for objects placed within the focal point, or with diverging lenses.
A concave mirror can produce only diverging rays if the object is placed within the focal point of the mirror.
When an object is placed obove the ground !is at rest !
Yes, a real image can be formed by a concave mirror when the object is placed beyond the focal point. A virtual image can also be formed when the object is placed between the mirror and the focal point.
The image formed by a concave mirror when the object is placed between the focus and pole is virtual, upright, and magnified. This image appears on the same side as the object.
In a simple microscope, the object is placed at the object focus point where the image is formed. This image is then magnified by the eyepiece lens so it can be viewed by the observer.
