A Green Wall Green Light And All The Other Visible Wavelengths – The visible spectrum of electromagnetic energy is a range. Light from 400 700 nanometers nm is called visible light or the visible spectrum because humans can see it light outside of this range may be visible to other organisms but cannot be perceived by the human eye. The star would therefore appear white a. Violet has the shortest wavelength and therefore carries the most energy whereas red has the longest wavelength and carries the least. The wavelengths of visible light that an object reflects or transmits determine the color that the object appears to the human eye. Light at the other end has a longer wavelength and appears red..
The human eye can distinguish only red green and blue light.
A green wall green light and all the other visible wavelengths. All other colors blue blue green green yellow and orange appear in the middle. If you study the illustration above you will see at the earth s surface almost all the wavelengths with any significant energy are visible see the. The photosynthetic pigments in leaves absorb all colors of visible light and then re emit the absorbed em energy as green light d.
You may ask yourself why is it that we only see the visible portion of light. A green star is radiating right in the center of the visible light spectrum which means it is emitting some light in all the possible colors. Black absorbs all visible light and is therefore that white which absorbs very little visible light and reflects it all back to the eye.
The visible and non visible light spectrum as you can see from the illustration above visible light is only a very small portion of all light waves. In terms of frequency this corresponds to a band in the vicinity of 405 790 thz. Electromagnetic radiation in this range of wavelengths is called visible light or simply light a typical human eye will respond to wavelengths from about 380 to 740 nanometers.
The color of the pigment comes from the wavelengths of light that are reflected or in other words those wavelengths not absorbed. Little green light is absorbed so it passes through and we see the leaves as green. The colors of visible light do not carry the same amount of energy.
All other colors of light can be created by combining the primary colors. They reflect green wavelength back to our eyes and absorb all the other wavelengths of visible light. Light at one end has a shorter wavelength and appears violet.
The human eye sees color over wavelengths ranging roughly from 400 nanometers violet to 700 nanometers red. The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Chlorophyll the green pigment common to all photosynthetic cells absorbs all wavelengths of visible light except green which it reflects.
Green plants some bacteria. Most of the other wavelengths of visible light are absorbed by photosynthetic pigments. Light that features all the visible wavelengths in roughly equal amounts.
At the other end of the spectrum toward red the wavelengths are longer and have lower energy. These three colors are the primary colors of light.
