The problem of the dispersion of light, what is the phenomenon of dispersion of light?

1. Red, purple, red light, red light, red light.

2. Approximately. 3. Black objects absorb all colors of light, petals are relatively soft, in order to survive and avoid high temperature damage, they absorb light with weak thermal effect, and reflect light with strong thermal effect; If it absorbs seven colors of light, it will be more damaged by high temperatures, and it will be difficult for the flower to survive. Therefore, black flowers are rare, while white flowers are common.

4 Leaves mainly rely on chloroplasts for photosynthesis, which do not absorb green light, so they appear green. (thus impossible to have black leaves).

Since white reflects all the colors of light, it is not conducive to photosynthesis. So the surface of the leaves is rarely white.

Red purple I don't know I don't know.

More than 13s black absorbs light, light produces heat, and the flower itself can't withstand it, and white reflection is no problem.

The reason for black is the same as above, white is reflective, and the leaves also have to absorb light and photosynthesis occurs.

So neither black nor white chlorophyll is also a reason.

I don't have a lot of power, I can't help much.

Dispersion of light refers to the phenomenon in which polychromatic light is broken down into monochromatic light.

Light consisting of two or more monochromatic lights (light consisting of two or more frequencies) is called polychromatic light. Light that can no longer be broken down (with only one frequency) is called monochromatic light.

Generally, white light (polychromatic light) can be passed through a prism to produce light dispersion. For the same medium, the higher the frequency of light, the greater the refractive index of the medium to this light. Among visible light, violet light has the highest frequency and red light has the lowest frequency.

When white light passes through the prism, the refractive index of violet light is the largest in the prism, and after the light passes through the prism, the deflection degree of violet light is the largest, and the deflection degree of red light is the smallest. In this way, the prism separates the light of different frequencies, which creates the dispersion of the light.

Principle

The principle of dispersion is the refraction of light. In nature, sunlight is white light. When the white light of sunlight passes through the prism and is decomposed into various colors of light, if the white screen is used to undertake, a colored light band is formed on the white screen, and the colors of these light bands are red, orange, yellow, green, blue, indigo, and violet.

The dispersion of light refers to the phenomenon of the decomposition of polychromatic light into monochromatic light. At the same time, dispersion is also a description of the relationship between the propagation parameter and the wavelength of an optical fiber.

Conditions under which light dispersion:

1. The light that can be dispersed must be a compound light, that is, a light composed of two or more monochromatic lights.

2. It has a medium that can make light refract.

3. Light is incident at a certain angle from the medium, resulting in the phenomenon of refraction.

The principle of dispersion is that polychromatic light is composed of a variety of monochromatic light, and each monochromatic light has its own frequency; The refractive index of the medium to different frequencies of light is different, when the polychromatic light is incident with the medium and produces refraction, because the frequency of each monochromatic light is different, the refractive index is different, so the refractive angle is different, at this time, each monochromatic light is emitted according to its own refraction angle, it will deviate from the light of other colors, so it will produce a rainbow-like color band.

The dispersion of light refers to the phenomenon of the decomposition of polychromatic light into monochromatic light. The phenomenon of polychromatic light being decomposed into monochromatic light through a prism; The phenomenon of optical pulse broadening in optical fibers caused by different group velocities of different frequencies in the spectral composition of the light source.

Dispersion is also a description of the relationship between a propagation parameter and frequency of an optical fiber. Newton was the first to observe the dispersion of light in 1666 using a prism and decomposing white light into colored bands (spectral wax nuclei). The dispersion phenomenon shows that the velocity of light in the medium v=c n (or refractive index n) varies with the frequency f of the light.

The dispersion of light can be achieved with prisms, diffraction gratings, interferometers, etc.

The dispersion of light refers to the dispersion phenomenon in which polychromatic light is decomposed into monochromatic light, the phenomenon that polychromatic light is decomposed into monochromatic light through a prism, and the phenomenon of light pulse broadening caused by different group velocities of different wavelengths of the light source spectrum in optical fibers. Dispersion is also a description of the relationship between a propagation parameter and wavelength of an optical fiber. Newton was the first to observe the dispersion of light in 1666 using a prism to decompose white light into colored bands.

The phenomenon of dispersion states that the velocity of light in a medium varies with the frequency of light. And the dispersion of light can be achieved with prisms, diffraction gratings, interferometers, etc. The dispersion of light proves that light has a fluctuating nature.

Dispersion, in a broad sense, refers to the phenomenon of decomposing polychromatic light into monochromatic light to form a spectrum. Several waves propagate in the medium, their frequencies are different, and the propagation speed is also different, this phenomenon is called dispersion; In physics, all phenomena related to wave velocity and wavelength are called dispersion. The ancient Chinese understanding of the dispersion phenomenon of light originated from the understanding of the natural dispersion phenomenon - the rainbow.

Dispersion can be achieved by using prisms or gratings as instruments such as "dispersion systems", when the polychromatic light enters the prism, because it has different refractive indices for various frequencies of light, the propagation direction of various colored lights has different degrees of deflection, so they are dispersed when they leave the prism to form a spectrum.

Because light of different wavelengths (different colors) is deflected at different angles (refractive angles) during refraction, therefore, in the process of refraction imaging, the light waves of different wavelengths emitted by a point light source cannot be well converged to the same position after refraction and separate different colors, which is usually called "dispersion".

The presence of dispersion makes it difficult to get a clear image.

The dispersion of light is the light that the sun decomposes into seven colors after passing through the prism, and this phenomenon is called the dispersion of light.

The reasons for the dispersion of light are as follows:

Sunlight is white light, which is a polychromatic light composed of seven monochromatic lights.

In addition, different monochromatic light passes through the prism with different degrees of deflection, with red light having the least degree of deflection and purple light having the largest degree of deflection.

Polychromatic light is decomposed into monochromatic light.

Dispersion of light refers to the phenomenon in which polychromatic light is broken down into monochromatic light. The phenomenon of polychromatic light being decomposed into monochromatic light through a prism;

After sunlight is refracted by a prism, there are red, orange, yellow, green, blue, indigo, and violet bands of color on the white screen from top to bottom, which is called light dispersion.

Application skills. The phenomenon of dispersion illustrates that white light is not monochromatic light, but is made up of a mixture of multiple colored lights
