Covering half of a converging lens reduces the amount of light entering the lens, causing the image formed to be dimmer. It may also lead to distortion or aberrations in the image due to the asymmetry in the lens. The focal point of the lens may shift slightly depending on which half is covered.

What happen to the image formed by a convex lens when half the lens is covered?
When half of a convex lens is covered, the image formed will be blurred and distorted. Light rays passing through the uncovered half of the lens will still converge to form a clear image, while the light rays blocked by the covered half will not contribute to the image formation. This can result in a partial or incomplete image being formed.
What happens when half the lens is covered with a black paper longitudinally?
The convex lens will form complete image of an object, even if its one half is covered with black paper. It can be understood by the following two cases. Case I When the upper half of the lens is covered In this case, a ray of light coming from the object will be refracted by the lower half of the lens. These rays meet at the other side of the lens to form the image of the given object, as shown in the following figure. Case II When the lower half of the lens is covered In this case, a ray of light coming from the object is refracted by the upper half of the lens. These rays meet at the other side of the lens to form the image of the given object, as shown in the following figure.
When you cover the top half of an object what happens to the image formed by a convex lens?
Covering the top half of an object will only allow the rays from the bottom half to pass through the lens. The image formed by a convex lens will still be created, but only for the bottom half of the object that is visible and the top half will not contribute to the formation of the image.
What will happen if cover half of the concave mirror?
If you cover half of a concave mirror, the reflected image will be dimmer, smaller, and less clear compared to when the mirror is fully uncovered. This is because the covered portion of the mirror is unable to reflect light, leading to a partial or distorted reflection.
What happens when half of concave mirror is painted black?
If half of a concave mirror is painted black, the reflective surface of the mirror will no longer be able to reflect light in those areas. As a result, the mirror will only be able to reflect light from the unpainted half, reducing its ability to form a clear image. This can distort the reflected image or create a shadowy effect on that half of the mirror.

When you cover the top half of an object what happens to the image formed by a convex lens?

How do you do half and half of two pictures?
From Image > Image Size you can resize picture size to its half.
What kind of image will be obtained if a convex lens is covered in the middle?
You can cover the center of a lens with a square or round or hexagonal piece of black paper, or cover part of its edge, or cover half of it, or drill a hole in it, or cut part of the lens off and throw it away. The only effect on the image will be to make it less bright, but its size, shape, color, or position won't change.
What will happen if cover half of the concave mirror?

As a result, the mirror will only be able to reflect light from the unpainted half, reducing its ability to form a clear image. This can distort the reflected image or create a shadowy effect on that half of the mirror.
How will the position and intensity of image will be affected if the lower half of the mirror is painted?
If the lower half of the mirror is painted, the image will only be visible in the upper half of the mirror. The intensity of the image will remain the same in the visible portion of the mirror, but it will be absent in the painted lower half. The position of the image will not be affected, as it will still appear at the same distance behind the mirror as the object is in front of it.
What is half of Earth covered with?

It divides something in half so that each half is a mirror image of the other?

When one half is a mirror image of the other half?
The shape is said to have lateral symmetry.
Is a new moon when only half the moon is covered?
