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.
What else can I help you with?
Where will be the image formed if the object is kept at the Focal in covex lens?
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.
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.
Where will the image be formedif an object is kept 15cm from the pole of a concave mirror of a focal length 20cm?
The image will be formed on the same side as the object in this scenario, since the object is within the focal length of a concave mirror. The image will be virtual, upright, and magnified.
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?
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.
O What kind of image do you see using a convex mirror?
A convex mirror will produce an upright, virtual, and diminished image of objects placed in front of it. The image will appear smaller than the actual object, making it useful for security purposes and in vehicles to provide a wider field of view.
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.

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!
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.
How you can see number of images formed by mirror?
As we place two mirrors inclined with each other then many images are formed. If @ is the angle of inclination then number of images is got by the formula [360/@] - 1 Hence as we place the two mirrors at right angles ie 90 degree then number of images will be 3 If both mirrors kept parallel facing each other then infinite images are formed.
When does convex lens act as a concave lens?
A convex lens acts as concave lens when it is kept in a medium whose optical density is higher than the lens itself. And the vice-verse is also true .i.e, a concave lens can act as convex lens too .
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
