What type of image is formed when object is kept at F for a convex lens?

For a convex lens the focal point is the transition point between getting a real image and a virtual image. If the object is at a greater distance then F you get a real image. If the object is closer to the lens then F you get a virtual image. If the object is located at F the light rays from the object leave the lens parallel and never form any kind of image.

A convex lens forms a real and inverted image of a needle at a distance of 50cm from the lensWhere is the needle placed in front of the convex lens so that the image is of the same size as the object?
A convex lens forms a real and inverted image of equal size only when it is kept at the center of curvature of the lens. The image is also formed at the center of curvature at the other side. Hence, the distance of object = distance of image = 50 cm. Now, focal length = � � radius of curvature = � � 50 cm = 25 cm Hope it is clear!
Where will be the image formed if the object is kept at the Focal in covex lens?
The image will be formed at infinite distance as parallel ray come out of the lens after refraction through lens.
Does a convex lens invert images?
Yes. Image formed by convex lens is laterally inverted. However, It should be kept in mind that convex lens can form both real and virtual images. If the object is placed beyond F (Focus), then real image will be formed and laterally inverted. However, if the object is placed between F and C. Then the images formed will be virtual but NOT laterally inverted. For concave lens, all images formed is on the same side so the images formed is NOT laterally inverted
Can convex lens have real and magnified image?
Yes it is possible. When the object is kept in between F and 2F, then an enlarged real but inverted image is got beyond 2F on the other side of the lens.
When an object is inside the focal point of a concave mirror what kind of image always results?
An upright image, which is called a virtual image. If the focal point was outside of a concave mirror, then it would be a real image, which is inverted.
O What kind of image do you see using a convex mirror?
we see a diminished and virtual image in a convex mirror provided the object is not kept on the focus of the mirror.

Why concave lens is the lens could correct the image formed of a nearsighted person?
Human eye is optical miracle.Depending on the distance of the object, we have to change the position of the screen.In case of human eye, screen (Retina) is kept at fixed distance and eye lens is elastic and it becomes more or less thin or thick, so as to adjust image on retina. This phenomena is called accommodation. In near sighted persons lens is more convex than it should be. So we put concave lens in front of eye, so that image of distant object should fall on retina. Human brain is also miracle and after few days, it starts guessing the actual distance of the object.
An object is kept in front of a concave mirror of focal length 20cm the image is 3 times the size of the object calculate 2 possible diastances of the object from the mirror?
40cm

Can convex lens diverge?
Yes if it is kept in a liquid with a grater refracting index than the lens
Why is personal account for a supplier kept?

Working principle of microscope?
microscope consists of two lens called eye lens and objective lens. objective lens is lens kept behind object and eye lens is keep on the top of microscope .i.e. on the place through which we look. firstly the object is placed behind the objective of microscope which is turned into virtual, erect and magnified image. later this image is thought to be the object for the eye lens and this objects forms real, inverted and magnified image.
