What is the brightest on paper when glazed?

Generally, it is a fluorescent coin, which is generally the most beautiful on bright paper, and it is also more transparent.

The brightest light we can see with the naked eye on Earth is an artificial laser, but there is light in the universe that is 10,000 times brighter than a laser. Some neutron stars emit much brighter light than lasers. Among them, the brighter cosmic emission light is orange, the brighter one is yellow, and the brighter one is yellow, blue, and light blue.

So the brightest light should be a pale blue cosmic light. Thank you.

Cow bile, this thing is not easy to find, but it is definitely a good thing to glaze, when I used to learn photographic magnification when I was a child, there was no glazing machine is to use cow bile to coat the glazing glass plate, and then the magnified ** is pasted on the glass, put it in the sun to dry, it is really very bright.

What is glazed on the paper will be cooler, you can apply some gloss agent or reflective paint on the paper, and its effect is also better.

What is written, it is also constantly sentenced. What is the brightest light on paper?

Hello friends, I think that substances like water are particularly reflective, and when it is on paper, the light will be very bright on it.

You can buy the metallic paint of that kind of car, that is, it is very bright after the hand spray paint is sprayed on the paper, and you can also spray a layer of bright gold oil on it.

Gray paper is brighter. Because light is fully reflected in a mirror, and diffuse on paper.

When viewed from the front, the mirror is bright, because the mirror is specular reflection, while the gray paper is diffuse; From the side, the gray paper is shiny.

Look at which angle you look at.

The light is fully emitted on the mirror, and it is brightest if it is seen from the direction of the reflected light, and it is not light when it is seen in the opposite direction.

The surface of the gray paper is rough and diffuse, and it looks the same from any angle, but it is impossible to look past the brightest situation in front of it.

If you hang a mirror on gray paper, it depends on where you stand.

If yes: mirrors. Person. Lamp.

If the light cannot be reflected from the mirror to the eye, then it is not bright.

Person. Mirror. Lamp.

The light is reflected from the mirror to the eye. It's very bright.

Mirror, because he reflects, gray paper does not reflect or less.

If you hang a mirror on gray paper, it depends on where you stand.

If yes: mirrors. Person. Lamp.

Person. Mirror. Lamp.

The light is reflected from the mirror to the eye. It's very bright.

Which angle to look at.

Light is emitted specularly on a mirror, and if it is seen from the direction of the reflected light, it is brightest, and if it is seen in the opposite direction, there is no light.

The surface of the gray paper is rough and diffusely reflective, which looks the same from any angle, but it is impossible to surpass the brightest case of the previous one.

Mirror, because he reflects, gray paper does not reflect or less.

Silver light pen, this font will be obvious after the light reflection of color!

Highlighter, write highlighter water on paper, and use ultraviolet light to show the characters.

(1) Sunlight rays to the earth, can be regarded as parallel light, sunlight is facing the convex lens, the sunlight at this time is parallel to the main optical axis, refracted by the convex lens and converged on the main optical axis, on the paper can get a minimum and brightest point, this point is the focus of the convex lens The focus temperature is very high, put the match at the focal point, the match can be ignited;

2) The small bulb is placed at the focal point of the convex lens, and the light hitting the convex lens is refracted by the convex lens and becomes a parallel ray

3) u f, into a real image; u f, the virtual image is formed so that the dividing point between the virtual image and the real image is double the focal length

U 2F, a handstand to reduce the real image; u=2f, it becomes a large real image such as an inverted stand; f u 2f, into an inverted magnified real image

Therefore, the dividing point between magnified and reduced images is double the focal length

So the answer is: focus; Focus; directional light; at double focal length; Double the focal length

1) The convex lens is facing the sun, the parallel sunlight is parallel to the main optical axis, and after being refracted by the convex lens, it converges on the main optical axis, which is the focus of the convex lens, and the distance from the focal point to the optical center is the focal length

Parallel sunlight converges into a point, indicating that the convex lens has a converging effect on the light 2) The concave lens has a divergent effect on the light, so the smallest and brightest spot cannot appear on the paper in Experiment 2

So the answer is: (1) focus; Focal length; Convex lenses have a converging effect on light; (2) No; Concave lenses have a divergent effect on light

1. Paste transparent frosted cellophane, rolls, in various sizes, stationery stores or places that sell decorative materials are sold, very cheap, and the back is self-adhesive, it is very convenient to paste. After pasting, the glass becomes a frosted glass effect, and the light transmittance is very good.

2. Paste a professional one-way translucent film, the cost is high, and the construction is more troublesome, but the effect is very good, and at the same time, it is heat-proof and ultraviolet-proof, which is more suitable for high-end places.

Glass Sticker Benefits:

1. Thermal insulation and energy saving, warm in winter and cool in summer: sunscreen and energy-saving film, equivalent to a 24 cm brick wall, can block 60% and 85% of the sun's heat in summer and reduce the indoor temperature by 3 6; It can be used to keep warm in winter.

2. Anti-ultraviolet rays: The glass film can block more than 99% of harmful ultraviolet rays.

3. Explosion-proof and shock-resistant: the toughness of the safety, anti-theft and heat-proof safety film and the super adhesion with the glass, even if the glass is smashed into pieces, it is still bonded into a whole, which greatly reduces the danger.

Paste light-colored paper, but the effect is not very large, you can use that kind of special sunshade cloth to hang on the window to prevent the sun from shining too strongly, but then the home will be very dark, after all, the sunshade cloth is all blocked.

It is recommended to use cellophane with a little white color, after all, it reflects various colors of light, and the light absorption is not very good, and it can also delay the service life of cellophane.

Glue a layer of cellophane to protect from light, and install a curtain to block out the light. If you use black paper, the room will be dark and will not be able to function as a window.

It is undeniable that thick, black paper has a better shading effect, and the outer surface has a better reflective effect.

One is glass reflective paper, one is glass film, depending on your own economic conditions or preferences, each has its own characteristics, generally to absorb ultraviolet rays of the glass film is better, not only does not block the line of sight, but also can have different colors to choose from, change the white and transparent situation of a single glass.

Generally, it is better to use a glass film that can absorb ultraviolet rays and not block the view.

One-way reflective heat insulation film, glass film, household window film, sun film, balcony sunscreen sunshade window stickers, search for them all in**.

With shading film, many places that sell building materials are sold, and you go to the local building materials to understand and understand before deciding. Or with curtains.

I don't know what you want to do with it, shading, heat insulation, privacy can be attached to the glass film, there are many models to choose from.

First: Sticking frosted paper (i.e., film) or single transparency on the glass can reduce direct light.

Second: Use blackout curtains, which are very effective, and when you pull them, the whole room will immediately darken.

Third: Install beautiful curtains around the bed where you are sleeping, and the sleeping atmosphere will be good.

There are special glass stickers, but that kind still leaks light.

You can buy the darker or thicker material, and it won't.

Cellophane, something like a plastic bag, is much better looking than a plastic bag, much better than the quality of a plastic bag, there are patterns on it, you can choose your own favorite pattern, and the glass store is basically available.

The silver stickers block out the sun and block a little bit of heat.

Now there are special shading ones, with a light-blocking coating added.

There are a lot of glass stickers, frosted, 3D, colored, beautiful, translucent shading of all kinds, you go to ** search and it will come out.

It is available online, but the darker the color, the better the shading effect.

Glass reflective paper or glass film is fine.

Pasting black paper can shade light!

What kind of paper doesn't all have that shade curtain now.

Sunlight rays to the earth, can be regarded as parallel light, sunlight is facing the convex lens, the sunlight at this time is parallel to the main optical axis, refracted by the convex lens and converged on the main optical axis, on the paper can get a minimum and brightest point, this point is the focus of the convex lens The focus temperature is very high, put the match at the focal point, the match can be ignited;

So the answer is: focus; Focus; Parallel
