A real image can be detected with tissue, ground glass, smoke,
fog, spray, CCD, or photographic film at the focal plane.
An image is formed by a convex lens when rays of light converge after passing through the lens. This forms a real image on the opposite side of the lens. The position and size of the image depend on the distance of the object from the lens and the focal length of the lens.
If the object is more distant from the lens than the focal length of the lens, a real image is formed.
Image formed by a concave lens or a diverging lens is virtual,upright and smaller than the object.It is used by short sighted people.
An image of that object formed by the lens of the eye on the retina.
A virtual and upright image is formed if the magnification is negative (-4.6) when using a lens.
The image produced is a real image if the object is located at infinity and the lens is a convex lens. The produced image can actually be placed on a screen and photographed.
the image formed by convex lens are real but the images formed by concave lens are virtual concave mirror are commonly used in to torches search light and vehicles headlights to get powerful parallel beam of light they are often used as a wing a to see a larger image of the face the dentist use a concave mirrors to see larger image of that is open send large can give are used to concentrate sunlight to produce heat in solar furnace
Virtual image
The image formed by a convex lens depends on the object distance from the lens, the focal length of the lens, and the object size. These factors determine whether the image formed is real or virtual, magnified or diminished, and upright or inverted.
In a concave lens the object always forms a virtual image. The convex lens also forms a virtual image.
The image of the tree formed by the convex lens is virtual, upright, and magnified.
If the object is placed at the focal point of a convex lens, the image will be formed at infinity on the opposite side of the lens. This is because parallel rays of light that enter the lens will refract and appear to converge at a single point after passing through the lens, leading to a virtual image being formed at infinity.
