Visible Light Spectrum Colors

Visible light spectrum colors. 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 colors of sufficiently close wavelengths are indistinguishable for the human eye. Without pigments or dye fabric fibers paint base and paper are usually made of particles that scatter white light all colors well in all directions. As a form of electromagnetic radiation light has properties in common with both waves and particles.

Violet has the shortest wavelength at around 380 nanometers and red has the longest wavelength at around 700 nanometers. As the full spectrum of visible light travels through a prism the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Essentially that equates to the colors the human eye can see. Color temperature is a characteristic of visible light that has important applications in lighting photography videography publishing manufacturing astrophysics horticulture and other fields.

It is also known as the optical spectrum of light or the spectrum of white light. Within red violet there is a continuous range of wavelengths. Below is the diagram of the visible light spectrum showing the constituent colors of the spectrum. A spectral color is a color that is evoked in a typical human by a single wavelength of light in the visible spectrum or by a relatively narrow band of wavelengths also known as monochromatic light every individual wavelength of visible light is perceived as a spectral color in a continuous spectrum.

The human eye sees color over wavelengths ranging roughly from 400 nanometers violet to 700 nanometers red. It ranges in wavelength from approximately 400 nanometers 4 x 10 7 m which is violet to 700 nm 7 x 10 7 m which is red. The electromagnetic spectrum is a range of frequencies of different energy waves such as gamma rays x rays ultraviolet rays visible light infrared waves microwaves and radio waves. 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 visible spectrum or color spectrum is a subset of the electromagnetic spectrum. In terms of frequency this corresponds to a band in the vicinity of 405 790 thz. The red color of light has the longest wavelength among the visible spectrum while the violet color of light has the shortest wavelength. It can be thought of as a stream of minute energy packets radiated at varying frequencies in a wave motion.

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. To understand colour therefore it is necessary to know something about light. Colour colour the visible spectrum. Newton demonstrated that colour is a quality of light.
