Why can t a magnifying glass magnify the corner?

Magnifying glass. You can only enlarge the parts of something proportionally, and the shape remains the same.

An angle is made up of two rays, and the magnitude of the angle is determined by the position of these two rays, that is, the degree of opening. After the angle is magnified by a magnifying glass, the thickness and length of these two rays are magnified, but the degree of opening does not change, and the angle remains the same.

The larger the viewing angle, the larger the image, and the more you can distinguish the details of the object. Moving closer to an object increases the angle of view, but is limited by the ability of the eye to focus. Use a magnifying glass to keep it close to your eyes and place the object in its focal point to form an upright virtual image.

The role of a magnifying glass is to magnify the viewing angle.

Magnifying glass magnification things, but one thing that magnifies anyway, is talking about the geometry of the "corners". Why is that? An angle formed by two rays is determined by the magnitude of the angle of the two rays at the location, i.e., the degree of opening.

The angle of the two rays of thickness and length magnified by a magnifying glass is magnified and does not change, but the range of the opening angle remains the same. The only thing about the magnifying glass is that the parts are large proportions, and the shape is unchanging. Mathematically, a pattern and a primitive figure enlarged in proportion to a similar shape are said to be "similar shapes proportional to their corresponding sides of similar shapes, and the corresponding angles are equal."

Something that cannot be magnified with a magnifying glass is the angle. A magnifying glass is a simple visual optical device used to observe the tiny details of an object, and is a converging lens with a focal length much smaller than the photopic distance of the eye. The size of an object imaged on the retina of the human eye is proportional to the angle (angle of view) of the object to the eye.

The magnifying glass cannot magnify the angle, according to the imaging principle of the magnifying glass, the object can be magnified in equal proportions, and after the angle is magnified in equal proportions, its degree is unchanged.

object in the retina of the human eye.

The size of the image is proportional to the angle (angle of view) of the object to the eye.

Principle

In order to see tiny objects or details of objects, it is necessary to move the object closer to the eye, which can increase the angle of view and create a large real image on the retina. But when the object is too close to the eye, it is impossible to see clearly.

In other words, it is necessary to be discerning, not only to make the object open at a large enough angle to the eye.

And it should be at the right distance. Obviously, for the eye, these two requirements are mutually restrictive, if a convex lens is placed in front of the eye.

This problem can be solved. A convex lens is the simplest magnifying glass, a simple optical instrument that helps the eye observe tiny objects or details.

No, this foot doesn't get bigger, because the magnifying glass is for small objects, so this corner doesn't get bigger.

Look at a corner with a magnifying glass again, and the size remains the same.

The phrase "look at a corner with a magnifying glass, and that corner gets bigger" is false.

The magnifying glass magnifies only the length of the two sides of the corner. The size of the angle has nothing to do with the length of the two sides, only the size of the opening on both sides of the angle, so after a corner is magnified by a magnifying glass, the degree of the angle remains the same. From the analysis, it can be seen that a corner will become larger after magnifying with a magnifying glass, which is wrong.

Magnifier imaging features1. The object and the image formed by the magnifying glass are on the same side of the magnifying glass.

2. The closer the magnifying glass is to the object within a certain range, the smaller the image is seen, and the farther away from the object, the larger the image is seen.

3. If the distance between the magnifying glass and the object is large to a certain extent, the resulting image will disappear.

4. The object seen through a magnifying glass looks like an upright and magnified virtual image.

Wrong.

Look at a corner with a magnifying glass, and the corner will not get bigger, but will remain the same. Although the magnifying glass magnifies the object, it cannot change the shape of the object, and therefore its relative position. The relative positions of the two rays that make up the angle under the magnifying glass do not change, that is, the angle at which the two sides of the angle open does not change, so the angle is still that large.

In addition to the meaning of truth, that is, the understanding is directly connected with the facts, and the true reflection and expression of the facts, objectivity as a noun refers to the nature, form and mode of existence of things. Objective cognition and subjective cognition are the two ways in which people perceive things, and people understand and obtain the world through these two methods, and these two methods become the two ways for people to reach existence.

An angle is made up of two rays, and the magnitude of the angle is determined by how far these two rays open. After the angle is magnified by a magnifying glass, the thickness and length of these two rays are magnified, but the degree of opening does not change Wei Sou, so the angle still does not refer to the change of the period.

When we look at things with a magnifying glass, we will find that the objects in the magnifying glass are usually magnified many times. However, if you take a magnifying glass and look at a corner, you will be amazed to find that the magnifying glass cannot magnify it anyway, it is still the original size, why is that?

An angle is made up of two rays, and the magnitude of the angle is determined by how far these two rays open. When the angle is magnified by a magnifying glass, the thickness and length of the two rays are magnified, but the degree of opening does not change, so the angle remains the same. As a result, a magnifying glass can only magnify the parts of something proportionally, without the same shape.

Mathematically, a proportionally enlarged figure is called a similar shape to the original figure, and the corresponding sides of the similar shape are proportional, but the corresponding angles are equal.

Magnifying the morning mirror can only magnify the parts of the thing in proportion, and the shape remains the same.

mathematically. A proportionally enlarged figure is called a "resemblance" to the original shape

The corresponding edges of the similar shape are proportional.

And the corresponding angles are equal!

The "angle" mentioned in geometry is composed of two rays, and the angle is too small to be determined by the degree to which these two rays open.

If the angle is magnified, the angular relationship of the rays changes, the shape is no longer similar, and the magnifying glass is no longer a presumptuous continental mirror, but will be called a cracked deformation mirror.
