in case of convex lense, when u place the object between focul length and pole, virtual image is formed behind the object at 25cm...
The image formed by a plane mirror is virtual image.
A real image is formed when light rays actually converge at a point, while a virtual image is formed when light rays only appear to converge at a point.
image formed by the concave lens will be erect , virtual and smaller than the size of object.
A real image is formed when light rays actually converge at a point, while a virtual image is formed when light rays only appear to converge at a point.
If an image can be formed on screen it is classified as real. Virtual images cannot be projected on an image.
The image formed by the convex mirror is virtual, erect and diminished.
A real image is formed when light rays actually converge at a point, while a virtual image is formed when light rays only appear to converge at a point when traced back.
If the object is more distant from the lens than the focal length of the lens, a real image is formed.
A real image is formed by a concave mirror when the object is placed beyond the focal point of the mirror. A virtual image is formed when the object is placed between the mirror and the focal point.
In a concave lens the object always forms a virtual image. The convex lens also forms a virtual image.
An image formed by a convex mirror is virtual, upright, and diminished in size. The image is formed behind the mirror, making it appear smaller than the object being reflected. Additionally, the image is not focused and does not produce a real intersection of light rays.
The difference is that when virtual image is formed by the concave mirror...it is larger than its original size..but when it is formed by the convex mirror..it is smaller than the original size....
