What is the device that separates refracted light rays?
? How does this lens differentiate light rays? There is a type of lenses that can affect the treatment of nearsightedness and it is called “regression”, or it can treat farsightedness, and this is called “hyperopia”, and we will show you all the important information related to answering these questions below.

What is the tool that separates the refracted light rays?

Answer

concave lens

come this The question is among the questions of scientific competitions, and the answer is the concave lensIt is a thick lens at the ends, but its thickness is less in the middle, in addition to the concave lens through which distant objects can be seen clearly, but the vision through it is not clearly visible to nearby objects.

But according to the principle of a squinted lens, we find that the maximum point of clarity of vision is called the imaginary focus, and the distance between the center of the lens and the maximum point of clarity is called the focal length.

concave lens formula

The lens formula is used to determine the nature and position of the image formed by a concave lens. The lens formula is expressed as:

• If the object’s distance from the lens =
  do
  following the image formed by the lens =
  from
  ..
  The focal length of the lens is calculated
  f
  By the equation through the following equation: 1/
  do + 1/di = 1/f

lens magnification calculator

We will learn the correct way to calculate the magnification of the lens in the following:

• If the length of the body =
  h o
  ،
  The distance of the body from the lens =
  do
  And
  Dimension of the image formed from the lens =
  hi
  ،
  The length of the image formed by the lens =
  from
  a
  So, calculate the magnification of the lens
  m
  In the following two forms:
  (
  M=hi / ho
  –
  m=-di /do)

Formation of the image in a concave lens

An object placed at infinity forms a virtual image when focusing. The image size is much smaller than the object size, and an object placed at a finite distance from the lens forms a virtual image between the pole and the focus of the convex lens.. As a result, the image size is smaller than the object size.

Concave lens uses

In the framework of the presentation of the answer to a question, what is the tool that disperses the refracted light rays? It is necessary to identify the most common uses of this lens to come as follows:

1- It is used in a telescope

Concave lenses are used in telescopes and binoculars to magnify objects. Because a convex lens creates a blurry vision, telescopes and binoculars manufacturers install concave lenses before or inside the lens, so that a person can focus more clearly.

2- It is used in glasses

Concave lenses are commonly used to correct nearsightedness, where the eyeball of a person with myopia is very large, so they are used in glasses that correct the deficiency by scattering light rays before they reach the eyeball, which enables the person to see things far away in a very clear way.

3- Used in the peephole

Door openings or door stops, which are used to maintain the security of the house, and they are safety devices that provide a panoramic view of things outside the walls or doors, and a concave lens is used, to reduce the size of the objects and give a wide view of the thing outside.

Method of differentiation of a concave lens for light rays

After we have indicated the answer to the question, what is the tool that disperses the refracted light rays? We find that the concave lens is one of the tools that disperse the rays of light, and make them appear clear from afar, but not visible from close.

In addition, the concave lens works to refract light.. For example: in the camera, where it works to break the light rays and reflect them outward, so the rays appear as they are coming from a smaller image, and they appear close to the camera compared to what they are in reality.

It also helps people with myopia, known as myopia, and usually suffer from not seeing distant objects, and accordingly it works to refract light rays outward, so that it appears as if it is close to the eye.

Lenses in general are made to help people with visual problems, and not only that, but they are also made for many other uses.
