When do convex lenses invert images?
Convex lenses invert images when the object is placed between the focal point and the lens. This occurs because the light rays converge towards a point beyond the lens, causing the image to be formed upside down.
How a lens magnifies an image?
A lens magnifies an image by bending light rays to converge at a focal point, creating a larger virtual image. This occurs because the lens creates a focused image that appears larger to our eyes. The curvature and refractive index of the lens determine the degree of magnification.
What is concave lens in a periscope?
A concave lens in a periscope is used to invert the image received from the object being observed. This type of lens helps to create a larger field of view within the periscope by expanding the image. The concave lens also helps to focus the incoming light rays onto the mirror system of the periscope for reflection.
Image of object formed by a lens on the screen is not in sharp focus suggest a method to get clear focusing of the image on the screen without disturbing the position of the object lens or the screen?
You could insert a second lens in the focal path, between the object and the first lens. The second lens can be designed (or moved) to focus the image on the screen. This is the same function that eyeglasses do for people with poor vision. The second lens, the eyeglasses, are inserted between the viewed object and the lens of the eyes. The second lens is designed to correct the distortion of the eye lens, thus creating an in-focus object on the "screens" of the eyes.
How is an image formed by a convex lens?
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.
Why do not we see inverted image though eye lens is convex?
our optic nerves invert the image and our brain reads it

What is the lens of the eyes?
the lens is what the eye uses to focus an image on the retina.function of the eye lense is is to adjust the focal length of the eye so it can make a real and sharp image of object
Why microscope produces inverted image?
The reason a microscope produces an inverted image is simply due to the number of lenses within it, or more specifically, the number of focal points it has. A microscope with a single lens will have a single focal point. Each focal point will invert the image once, meaning that a microscope with a single lens will produce an inverted image. If you were to add another lens to the microscope and align it the proper distance from the first lens, it would be possible to reorient the image to be right side up. As a side note, our eyes work the same way, the images coming into our eyes are inverted by our own lenses, its up to our brain to flip things right side up.
How does the image form in the eyes?
The cornea and the lens focus the light on the retina - but the "image" you see is formed in the brain from just parts of the light image that exists in the eye.

Is cartilage present in your eyes?
No, cartilage is not present in the eyes. The eyes are made up of specialized tissues such as the cornea, retina, and lens, but cartilage is not a component of the eye structure.
Why is the image in your eye produced upside down before it is flipped by the brain?
if there is an object before a lens at a distance more than its focal length and is surrounded by a rarer medium it always forms the image on the other side of lens and is inverted w.r.tobject. our eye lens will simply act like a biconvex lens whose focal length is around 2.5cm . there fore images formed on the retina will be inverted and they are made upright by the brain system.
Why are today microscope called compound scopes?
Because the magnification of image = magnification of eyes piece * magnification of lens.
How is an image formed by a convex lens?
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.
