The spectral colors are also called rainbow colors. The frequency of visible light varies from 4 × 10 14 to 8 × 10 14 Hz, and the wavelength of visible light varies from 380 nanometers to 740 nanometers. The visible light falls between the range of the ultraviolet and infrared regions. These are radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays, and gamma-rays. This broad range of wavelengths of the electromagnetic radiations is called the electromagnetic spectrum.Įlectromagnetic spectrum is divided into seven regions in the increasing order of frequency and decreasing order of wavelength. The colors which contain only one wavelength are called pure colors or spectral colors.Įlectromagnetic radiations are transmitted in the form of waves of different wavelengths and frequencies. Here, the spectrum doesn't contain the entire colors, which can be distinguished by the human visual system.įor example, unsaturated colors like pink, or purple variations like magenta are absent because these colors can only be made from a mixture of multiple wavelengths. Considering the frequency, this corresponds to a band frequency between 405 to 790 THz. Wavelengths of the range of between 380 to 740 nanometers are perceivable to human eyes. The wavelength of electromagnetic radiation visible to the human eye is called visible light or simply light. Visible spectrum is a field of the electromagnetic spectrum that is visible to the human eye. When all the colors (i.e., all frequency and wavelength) come together, they form the normal 'white' light. Visible light forms all the colors of the rainbow.Įach color has a different frequency and wavelength. Some other sources of visible light include television and computer screens, fireworks, and glow sticks. The sun, candles, light bulbs, and fire are the things that usually come in people's minds when they think of light, but visible light is produced from many sources in many different colors. Anything that glows or produces light has waves of visible light.

Visible light is that section of electromagnetic waves that is perceivable to human eyes.

In this article, we will get to know about the visible spectrum, wavelength, and colors. People always see the visible light spectrum, however, some people may be aware of it.

Radio waves are larger than light waves
