Light is made up of several colors What determines the different colors of light

It is composed of three primary colors: red, yellow and blue.

What is Ultraviolet Light? How can it be used in life?

Generally speaking, the selection of the three primary colors can be arbitrary, as long as the three-color mix can cover as many areas of the ignition-burning color as possible.

The three primary colors of light that are commonly set at present are:

The three primary colors of optics: red, green, and blue.

Colors combined: red and green equal to yellow; Green and blue are equal to cyan; Red and blue are equal to magenta; Red and green and blue are equal to white.

The colors written here are all macros and voids, and they are 100% superimposed colors. As they are stacked in different proportions, different colors are produced.

The wavelength of light determines the color.

The following are the wavelengths of various colors of light, red 620nm--760nm, orange 592nm--620nm

Yellow 578nm-592nm

Green 500nm - 578nm

Cyanine 464nm--500nm

Blue 446nm - 464nm

Violet 400nm--446nm

The color of light is determined by the wavelength and can also be considered to be determined by the frequency when the medium is constant. Because for describing the nature of light, the frequency and wavelength are the same. The speed of light = the frequency of light The wavelength of light, and the speed of light is a constant, so the wavelength of light and the frequency of light are one-to-one.

The wavelength of the same kind of light changes in different mediums because light will have different speeds of light in different mediums. Color is a visual effect on light that is produced through the eyes, the brain, and our life experiences. Light enters a different medium and cannot be perceived by our brain, so there is no color, and our eyes can only stay in the air, so only the light in the air has a concept of color.

Different colors of light have different wavelengths, and here are the wavelengths of various lights::

1. Red light: wavelength range: 760 622 nm;

2. Orange light: wavelength range: 622 597 nm;

3. Yellow light: wavelength range: 597 577 nm;

4. Green light: wavelength range: 577 492 nm;

5. Glaucom: wavelength range: 492 450 nm;

6. Blue light: wavelength range: 450 435 nm;

7. Violet light: wavelength range: 435 390 nm;

Factors that determine the wavelength of light:The wavelength of light is determined by both frequency and wave velocity. The frequency-closed beat rate of light remains constant during propagation, which means that the frequency does not change and the wavelength changes as the light passes through different mediums.

Therefore, the wavelength of light is determined by the frequency (color) of the light, as well as the medium through which it travels.

The formula for calculating the wavelength of light:The wavelength formula is wavelength = wave velocity frequency, i.e. = v f (where v is the wave velocity and f is the frequency, is the wavelength). The frequency is determined by the wave source, that is, when the wave is born; The speed of the wave is determined by the medium, that is, when the wave travels.

"Red, orange, yellow, green, blue, indigo" is a more accurate result based on the dispersion experiment of light. So it's the former that's more precise. But it's all right.

In physics, it is called red, orange, yellow, green, blue, indigo, violet, and seven colors of light, while in art, it is red, orange, yellow, green, blue, and violet.

Red, orange, yellow, green, blue, indigo, and violet will appear white when focused at one point, because sunlight is a composite light of the seven types of light: red, orange, yellow, green, blue, indigo, and violet.

If a light contains light of different frequencies, it is a composite light.

In fact, most of the light we can see is compound light. Sunlight, incandescent light, and fluorescent light are all composite lights, and only laser light or synchrotron radiation, or atomic spectrum, etc., are monochromatic light. The fire is also a composite light. Any composite light passing through a prism will be dispersed.
