2024年12月16日 · Colours of the spectrum are called chromatic colours; there are also nonchromatic colours such as the browns, magentas, and pinks. The term achromatic colours is sometimes applied to the black-gray-white sequence.

2016年8月10日 · 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. Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.

2021年1月16日 · The visible light spectrum is the region of the electromagnetic spectrum that human eyes see. It runs from wavelength of about 400 nanometers (nm) at the violet end of the spectrum to around 700 nm at the red end of the spectrum.

The visible spectrum is a small portion of the electromagenetic spectrum, but it encompasses all the photons we can see, which we call light. It only ranges from 400nm to 700nm (there are a million nanometers in one millimeter, so we can only see a range covering 3/10,000th of a millimeter in different wavelengths).

Full-spectrum light is light that covers the electromagnetic spectrum from infrared to near-ultraviolet, or all wavelengths that are useful to plant or animal life; in particular, sunlight is considered full spectrum, even though the solar spectral distribution reaching Earth changes with time of day, latitude, and atmospheric conditions.

A spectral color is a color that is evoked by monochromatic light, i.e. either a spectral line with a single wavelength or frequency of light in the visible spectrum, or a relatively narrow spectral band (e.g. lasers).

The visible part of the electromagnetic spectrum is also called a colour spectrum as it consists of seven colours which are arranged from higher energy to lower energy values. Visible colour light is located in the middle of the spectrum. It comprises a very small fraction of the overall electromagnetic spectrum. Recommended Videos

2023年9月14日 · The spectrum of wavelengths we can see (visible light) ranges from 380 nm (blue) to 700 nm (red). Below this spectrum is ultraviolet, after which we have blue, and at the top of the spectrum of visible light is red, after which we have infrared.

The visible spectrum derived from electromagnetic radiation encompasses the 7 main color bands detectable by human vision: red, orange, yellow, green, blue, indigo, and violet. These colors have specific wavelength ranges and frequencies.

Spectral colors are generally produced by monochromatic light i.e. visible light of a single wavelength. The spectrum appears continuous. Therefore, there are no definite boundaries between the colors. However, the approximate ranges of wavelength and frequency can be used to specify the difference.
