colour physics

Color Physics 712 words color physics, Distributes sunlight into spectral colors. (Jazz Isaac Newton 1676) discusses Newton's experiments and subsequent experiments from particle to wave theory. Refers to light that examines how an eye is looking at colors, is identified, described, emitted, transmitted, and reflected. Sir Isaac Newton thinks that light is made of small particles. At the same time, Christiaan Huygens thought that light consists of waves oscillating up and down perpendicular to the propagation direction of light.

Creatures come in two colors: pigment (chemical) and structural color (physical). Dyes are produced in the outer layers of organisms by biochemical reactions. Structural color originates from a microscopic physical pattern on the surface that interferes with incident light by diffraction or other optical processes and some bird feathers and butterfly feathers have a particularly vivid structural color. Unlike the structural color, the color of the pigment does not change depending on the viewing angle, but in many cases the chemical substance causing it decomposes soon after death, but the structural color is more resilient. In fact, as the beetle from Messel, Germany, of 47 million years ago showed, the physical model sometimes survived fossilization. They are very similar to today's living scarab beetle and jewel beetle.

The physical phenomenon that produces a structural blue resembles a phenomenon that produces a rainbow-colored substance, as seen in the head of a magpie or a male wild duck, but it is not the same. The color of rainbow-colored feathers is due to interference, due to constructive enhancement of lightwave interactions or destructive elimination of specific wavelengths and colors. For example, even though the oil is colorless, the thin oil film on the water will produce a rainbow-like bright color due to this light interference phenomenon. These colors are called film interference colors. Likewise, rainbow-colored feathers are usually very bright and colorful compared to the blue structure feathers observed under the same light.

The color we see is actually light waves, and all substances absorb and reflect light to a certain extent. The object represents the color of the part of the light that reflects, but it does not appear to absorb the color to absorb. It is characterized by pigmentation. For example, hemoglobin is a dye that stains red and anthocyanins in our blood, bringing different colors of red to tomatoes, grapes, and beets. For example, blue vibrates at a relatively high frequency, red slowly vibrates, red light is darker than blue. Purple has the shortest wavelength and highest frequency among all colors. Light passes linearly through space, but over the centuries it has been known for many centuries that as the sun passes through the glass prisms, the colors bend to different degrees and produce different lights - rainbow
