How to make the surface of the object reflect like a mirror

Compared with solids and liquids, liquids have a prominent macroscopic characteristic that they do not have a certain shape and have fluidity. However, it has a certain volume and is not easy to compress, which is relatively close to solid in this regard. From a microscopic point of view, the molecules inside the liquid are also densely packed, the molecular spacing is small, and the intermolecular interaction force is large.

The movement of liquid molecules is mainly manifested as small vibrations near the equilibrium position, and in a small area, the liquid molecules are arranged in a regular manner. However, liquid molecules are different from solid molecules, and liquid molecules do not have a long-term fixed equilibrium position, and they are constantly moving, resulting in liquid fluidity.

Liquids have many properties that distinguish them from solids and gases, and today only the properties of the surface layer of the liquid in contact with the gas and some properties of the contact layer of the liquid with the solid are studied.

1 Surface phenomena of liquids.

1) Demonstration experiment: In the rectangular glass cylinder, the lubricating engine oil is suspended in a spherical shape in a mixture of water and alcohol.

We know that among the various shapes of the same volume, only the spherical object has the smallest surface area. The lubricating oil is spherical in the mixture, indicating that the surface of the liquid has a tendency to shrink to a minimum.

Demonstration experiment: Experiment with soapy water to prove that the liquid level has a tendency to shrink.

Tie a cotton thread to the wire (the cotton thread should not be tightened), after the wire loop is soaked in soapy water, a soapy film appears on the ring, and any part of the soapy film on the wire loop and on both sides of the cotton thread is punctured with a hot needle, causing the cotton thread to be pulled into an arc by the film on the other side, and the cotton thread is tightened.

Tie a cotton coil to a wire loop so that the ring is covered with a film of soapy water. If you puncture the inner part of the cotton coil with a hot needle, the outer film will tighten the cotton thread into a circle.

The above experiments show that the surface of the liquid tends to shrink like a tight rubber film.

2) Microscopic explanation of the shrinkage tendency of the liquid surface.

A thin layer is formed on the surface where the liquid comes into contact with the gas, which is called the surface layer. Because the surface layer is above the gas, the liquid molecules in the surface layer are less affected by the surrounding molecules than the molecules inside the liquid, and the molecules in the surface layer are sparser than the molecules inside the liquid, so that the intermolecular gravitational force in the surface layer is greater than that inside the liquid. The intermolecular gravitational and repulsive forces in the liquid are in equilibrium, while the surface layer has a tendency to shrink due to the large molecular gravitational force in the surface layer.

Simple, micron-level machining lathe, this CNC machine tool cuts out metal or something like a mirror. However, this kind of machine tool is very expensive, not to mention before, it is said that the current domestic machine tool has not caught up with foreign countries.

One-way see-through glass (also called atomic mirror, single-sided mirror, one-way glass, one-way visible glass, etc.) is a kind of visible light apparatus.

Special glass with a very high reflectance ratio.

Unidirectional see-through glass must have a reflective surface facing the light or facing the exterior side when in use. When the outside is brighter than the indoor, the one-way perspective glass is similar to a normal mirror, and the outdoor scene cannot be seen from the outside, but the outdoor can be seen clearly.

Scenery. When the outdoor is darker than the indoor, the outdoor can see the indoor scene, and the indoor can also see the outdoor scene, and its clarity depends on the intensity of the outdoor illumination. Unidirectional see-through glass is mainly suitable for concealed observation windows

holes, etc. It is widely used in prisons, interrogation rooms of public security and law enforcement institutions, psychiatric hospitals, research rooms of university research institutions, and large conference rooms. High-end offices, monitoring rooms, etc. With a certain lighting effect, it can be achieved that the outside cannot see the inside, and the inside.

The effect can be seen from the outside. Please adopt it from the landlord.

Isn't it called a mirror if it transmits light on one side, otherwise it is called a glass window.

Summary. Any object can reflect light.

First of all, for light, there are two kinds of absorption and reflection in any object"action".Mirrors emit the vast majority of light and absorb very little. Another example is that objects with rough surfaces absorb most and reflect a few.

No object can absorb but not reflect at a time, or only reflect but not absorb.

In addition, it is also related to the degree of color: there is less reflection in the dark color, and more reflection in the light color.

What other objects can reflect light than mirrors?

water, paper (diffuse), glass, etc.

You can buy a box of petroleum jelly oil, which is the white kind, and apply it evenly on the mirror surface, so that the mirror surface is not so reflective, and it does not affect the use.

Hello, please go to the mobile phone to set the display backlight time, adjust it to 30 seconds or 15 seconds.

When the phone is not operating, the screen will automatically turn off after 15 or 30 seconds. You try it.

Anointment forehead. It's not bad to straighten it.

Paste the glass film will not reflect the light, but also paste the paper-cut window grille, even if it is reflective after most of the blocking, it will not have much impact.

1.Do not close the cage.

2.When he called, he pointed his finger at him and said no, be very serious.

It is a natural beauty, and it makes you content and happy.

Now most of the screen saver film costs less than 10 yuan, and it is impossible to have a good protective effect. Being in front of the computer for a long time hurts your eyes. If you notice that sometimes your eyes get watery, be sure to get away from your computer and take a break.

Either there is a chance of causing transient blindness. Always look at the greenery and look into the distance. Helpful for the eyes.

Mirror screen, as long as the front is not facing the sun, the reflection will not be bad.

Listen to reflective film, there is no need.

It can be used as a protective film, or directly, a protective film can be veneered.

Hehe. Give a suggestion! A person walks at night. Lie down until you're tired. The second one is not for you; How about the first look?

Don't think about the things that make you sad. Oh.

a) first draw the normal through the incident point, the angle of incidence is 90°-60°=30°, and then draw the reflected ray on the other side of the normal according to the reflection angle is equal to the angle of incidence, b) first draw the normal through the reflection point, the reflection angle is 90°-45°=45°, and then draw the incident ray on the other side of the normal according to the reflection angle equal to the angle of incidence, c) the normal divides the angle between the incident ray and the reflected ray, and the normal is perpendicular to the plane mirror, at this time, the angle between the incident ray and the reflected ray is 90°, That is, the sum of the angle of incidence and the angle of reflection is 90°, so the angle of incidence is 45°, as shown in the figure, MN is a plane mirror, and the angle of incidence is 45°

Physical] specular and diffuse.

More than 300 years ago, glass mirrors were invented. Attach the shiny tin foil to the glass surface and pour the mercury over it. Mercury is a liquid metal that dissolves tin into a viscous, silvery-white liquid that adheres tightly to the glass plate.

The glass mirror was a big step forward from the bronze mirror, and it was very popular, and for a time it became a treasure that the princes and nobles competed to buy. At that time, only the Venetian workshops could make this new type of glass mirror, and all the countries of Europe went to buy it, and wealth poured into Venice like a tidal wave. The Mirror Workshop was concentrated on the island of Murano, and was heavily cordoned off on all sides.

Later, the French ** bribed four Venetian mirror craftsmen with a lot of money and secretly smuggled them out of the country. Since then, the mystery of the mercury glass mirror has been revealed, and its value is not so noble.

However, the ability of mercury-coated mirrors to reflect light was not very strong, it was time-consuming to make, and mercury was poisonous, so it was later eliminated. Now the mirror, the back is a thin layer of silver. This layer of silver is not coated or electroplated, it is coated by the chemical "silver mirror rotten reaction".

Add glucose water to the ammonia solution of silver nitrate, and the glucose reduces the invisible silver ions into silver particles, which are deposited on the glass to make a silver mirror, and finally painted with a layer of lacquer. When you see Feng Li Hunger here, you will say, "The thing that shines on the back of the mirror is not mercury, it is silver."

This conclusion is behind the times again! In recent years, many mirrors in department stores have been aluminized on their backs. Aluminum is a silvery-white shiny metal that is much cheaper than precious silver.

The manufacture of aluminum mirrors is to evaporate aluminum in a vacuum, and the aluminum vapor condenses on the glass surface to become a thin layer of aluminum film, which shines brightly. This kind of aluminum mirror is inexpensive and promising. In this way, you will say:

I can't imagine that a small mirror is also developing and changing! There are several chemicals on the back of it alone. ”

Since light waves have the nature of wave particles, when the light shines on the mirror, the light waves are like countless football shots on a wall, and they will produce the same reflection angle as the incident angle with the different angles of incidence. That is, the reflection is like a football reflected back, making the mirror glow.

Hello, any object is reflective, there is no such thing as a substance that is absolutely not reflective. Rough surfaces, such as blackboards, diffuse reflection of light, while smooth surfaces, such as mirrors, specular reflection of light.
