The two mirrors are closely overlapped, and what is seen inside is 30

If they overlap, then you can't see what's inside, only the mirror.

The crux of the question is not the loss of light, but how far away is the horizon of the person.

Leonardo da Vinci discovered the perspective method very early, that is, people will feel that the parallel lines on the object will disappear at a certain point in the distance, and the application of this principle in painting can make the picture more three-dimensional.

The image in the mirror is a painting to a person, and it should have a perspective effect that is completely in line with the person's vision and a picture that is completely in line with reality, so it looks like the real thing.

Then the image in the mirror also follows the principle of perspective, and the parallel light will seem to disappear at a certain point in the distance in the person's observation. After this point, people cannot feel the existence of images.

So theoretically, n (number of images) = l (distance of the horizon) s (distance of the mirror).

The average person's visual range is 1500-2000 meters. Then a total of 1500-2000 images will be produced (if the light is strong enough).

In fact, it will be affected by two factors:

1.Light is lost in each reflection, about 10%-15% each time, and can be reduced to 8%-10% with plexiglass

2.It is the resolution and sensitivity of the human eye to light.

So you can usually see 10-16 images.

It's snowing, and it's white. Snow falls on the branches, blades of grass, stone steps, and various buildings as if covered with a thick white quilt. The twig smiled and bent over, and the grass bowed her head shyly.

I saw that the water in the lake was thick and slippery, and I would fall if I was not careful. Before the lake freezes, you can see the aquatic plants at the bottom of the water, and you can see colorful small fish, and you can reflect your own portrait like a mirror. Now the lake is frozen, and there are people in fancy clothes slipping on it to leak ice.

Some people laugh, some fall, and some slowly walk step by step like babies learning to walk.

The mirror can reflect the light, and you can also see your own face and yourself. But there are many people in this society who have been blinded by the 'heavy snow', frozen limbs, and coagulated blood. I really want to prove that I am busy, I have no time, I have money, I can't leave, I have many meetings, I can't do without you, etc., it's not that the world is too busy, it's not that time is too fast, it's not that I forgot my way home, it's that the snow comes too fast.

The mirror suddenly fogged up, and I couldn't see the other side of my mirror clearly. And anxious and busy.

Winter is here, and summer is coming. In summer, it can absorb more water vapor and keep the mirror from blurring. The rising sun shines on the earth in the morning to revive all things, and it is also the beginning of another night that can be approached.

The other side of the mirror can be a smiling, sunny, cute, and motivated you.

The ordinary mirror used in the home is a flat mirror. It is made by silver plating on one surface of a piece of glass.

If the glass is too thick, "ghosting" will occur when you look in the mirror. This is because the light rays from the object towards the mirror are reflected twice at the same time: on the front surface of the mirror glass and on the mercury surface behind the mirror glass.

In order to avoid ghosting, the glass should not be too thick.

In fact, the front surface of the glass is not as reflective as the mercury surface behind the glass, so it is not easy to see ghosting. )

The number of images that can be seen by two mirrors is related to the angle between the two mirrors.

If the angle between the mirrors is n°, the number of images that can be seen = (360 n)-1

When the mirrors are parallel, n=0, the number of images seen is infinite.

It is a phenomenon caused by mirrors reflecting each other and reflecting again.

It's because of the multiple specular reflections of light that enter the human eye.

Because the mirror will always reflect the image

The function of the mirror is to mirror the mirror, and when two mirrors are opposed, the mirror image will be infinite.

It's because you have too many distractions, and the old man can't see anything

You may see yourself 360 degrees. Because if the two mirrors are fixed, there will be blind spots in 360 degrees.

The first is to bring a microscope, be good at seeing the subtleties, and crack the phenomenon of "no snow and grass". If there is a lot of snow on the grassland, you will see a vast white patch, but you will not see the grass. If the law enforcement inspection sees more aspects of the results, it will not see the problem, not that the problem does not exist, but that it is covered up by the results.

In the inspection of law enforcement, due to the short time, the content we see is not complete, therefore, it is easy to be confused by the enumeration of achievements of the relevant departments, and cannot trace the root cause through small links, check out the problems, this kind of small eyes, with a microscope to see the problem, not only cultivate a thorough and meticulous work style, but also conducive to a comprehensive understanding of the implementation of the law, can overcome the phenomenon of "no snow and grass" in the work of law enforcement inspection.

The second is to bring reflectors, pay attention to the head of the acre, and crack the phenomenon of "the boat is too horizontal". It is a natural phenomenon that the boat crosses the level, that is, as soon as the boat comes, there is movement on the water surface, and as soon as the boat passes, the water surface quickly returns to calm. In the process of law enforcement inspection, there is also this situation, when the investigation attaches great importance to it, it is lively, and after the investigation, the wind and waves are calm, and no one cares about the problem.

This is mainly due to the use of old routines and old practices in law enforcement inspections, and everyone knows it, looking at the scene, turning over the data, listening to reports, not really hitting the hard, not investigating in advance, analyzing the matter, "looking back" after the fact, not using "reflectors", and specifically looking at the situation after the law enforcement inspection. If we let the implementation of rectification and reform after each law enforcement inspection activity kill a few more "return to the suspicion and patience of the gun", the phenomenon of "passing the level" of law enforcement inspection may gradually disappear.

The third is to bring a telescope, focus on the long-term, and solve the phenomenon of "one leaf obstructing the eye". In the supervision work of the people's congresses, the short-sighted phenomenon of "blinding the eyes of a leaf and not seeing the Taiqin Shed Mountain" often appears, and this is not a deliberate cover-up by the objects of supervision, but the fact that the supervisors do not have a "telescope" that can see the future through the present and see the essence through the phenomenon.

In the course of law enforcement inspections, it is often recommended to rectify what is found, and it is often impossible to put forward any suggestions and opinions on problems that have not been found or may occur, especially for problems that do not conform to the actual situation and are not strong in the specific implementation of the law, and cannot put forward better opinions and suggestions.

To break the phenomenon of "one leaf of obstacle" in law enforcement inspection, we need to conduct in-depth research, carefully analyze the occurrence and development of the inspection object, especially to study the potential impact of existing problems, not only pay attention to the benefits brought by short-term behavior in the moment, but to base ourselves on the long-term, broaden our horizons, and examine and study the main causes of problems in law enforcement inspections and the fundamental measures to solve them from a higher starting point and standards.
