An image which cannot be formed on a screen is said to be a virtual image. A virtual image is formed when light rays diverge after reflection or refraction and they do not actually pass through the position of the image. Therefore, the image cannot be projected onto a screen or captured on a surface. Virtual images are always erect and cannot be focused. Examples of virtual images are the images formed by a plane mirror or a convex lens when the object is placed inside the focal point.
