Physical Dispersion Is white light transparent?

Substances are transparent and opaque.

Light does not belong to matter, but to electromagnetic waves, so there is something wrong with the question you are asking.

Addendum: The color of a transparent substance is determined by the color of the light it can transmit.

What logic! If the white light is transparent, it should still be pitch black at night. According to the principle of non-influence of waves, all light is transparent, and the color of light is determined by its wavelength, but it does not contradict transparency.

White light is polychromatic light, which is composed of seven different monochromatic lights, which are red, orange, yellow, green, cyan, blue, and violet.

To say light is not to say transparent.

It is transparent glass that does not filter any light, not that the light is transparent.

Forehead. No. Composite light doesn't have to be white, understand?

Red light will turn black on blue because blue can only reflect blue light;

Blue light is still blue on blue because blue reflects blue light;

White light is blue on the word blue because white light can be broken down into seven chromatic light, where blue light is reflected and the rest of the colored light is absorbed.

The red light is still red on the red letter, because the red word reflects the red light;

Blue light is black on red because red can only reflect red light;

White light is red on red because white light can be broken down into seven colors of light, where the red light is reflected and the rest of the color light is absorbed.

There are no words in red and black.

There are no words on the blue paper, and there are no words in black letters.

White paper, blue letters, red letters.

When irradiated with red light, the words written in the red pen reflect the red light and cannot be seen clearly, while the blue characters can be seen clearly.

When irradiated with blue light, the words written in the blue pen reflect the blue light and cannot be seen clearly, while the red characters can be seen clearly.

It depends on the ratio of the various colors of light.

With the right proportions, you can get white light.

Red mixed with blue is pink.

The Three Primary Colors of Color and Light – The Principle of Additive Color Method The human eye recognizes colors based on the wavelength of the light they see. Most of the colors in the visible spectrum can be made up of three basic colors mixed in different proportions, and the colors of these three basic colors are red, green, and blue. When these three types of light are mixed in the same proportion and reach a certain intensity, they appear white (white light); If the intensity of all three types of light is zero, it is black (darkness).

This is the additive color principle, which is widely used in active light-emitting products such as TVs and monitors.

The colors add up to black.

White and any color add up to any color.

White light reflects all light--- what color of light shines on a white object, what color of light appears: for example, blue light shines on a white object and shows blue;

Black absorbs all light--- and any color of light is black on black: for example, blue light illuminates black objects;

Other colors reflect the same color as their own light, absorb other colors of light: blue anti-blue light, absorb other light: such as:

When blue light shines on a blue (white) object, it appears blue, and when it shines on an object of color other than these two, it appears black; Another example: red light appears red when it hits a red (white) object, and black when it hits a color other than these two.

(1) The white light passes through the prism, and on the other side of the prism, the light is decomposed into 7 kinds of monochromatic light from red to violet (2) These monochromatic lights of different colors are incident at the same angle of incidence, and the degree of deflection is the largest for violet light and the smallest for red light.

3) If the same prism is placed on the propagation path of these separated monochromatic lights, the light will still be transmitted as white light after passing through.

4) Therefore, white light can be divided into several different colors of monochromatic light by a prism, and this phenomenon is called light dispersion.
