Red, green, and blue are known as the primary colors of light. The combinations of two of the three primary colors of light produce the secondary colors of light. The secondary colors of light are cyan, magenta, and yellow.

Others purchase only the primary and secondary colors, and mix the tertiary colors themselves. Black, white, and grey are considered neutrals. They can be used alone to add depth and contrast to a painting. In addition, they can be mixed into any other color to create shades, tones, and tints.

A color produced by mixing two additive primary colors in equal proportions. The secondary colors are cyan (a mixture of blue and green), magenta (a mixture of blue and red), and yellow (a mixture of green and red).

See what happens when you mix together the three primary colors of light: red, green and blue.

The three primary colors for addition are red, green, and blue. When two primary colors are shined on a white object, it appears to be the complementary color of the third. TVs make purple using red and blue light.

As light passes through a prism, it is bent, or refracted, by the angles and plane faces of the prism and each wavelength of light is refracted by a slightly different amount. As a result, all of the colors in the white light of the sun separate into the individual bands of color characteristic of a rainbow.

dispersion of light

Dispersion of light: The splitting of white light into seven colours on passing through a transparent medium is called dispersion of light. The dispersion of white light happens because the angle of refraction of lights of different colours is different while passing through the transparent medium.

dispersion

When a beam of light enters a prism it gets refracted and splits into its seven constituent colours. This splitting of the light ray occurs because of the different angles of bending of each colour. Hence each colour passing through the prism bends at different angles with the respect to the incident beam.

Answer. when passing through aprism, dispersion of light (white light) happens wherein it splits into it’s seven constituent colours. Different colors of different wavelength experience different degree of deviation and hence when put through refraction,white light splits into its constituent colors.

violet

Answer. Answer: Visible light is a form of electromagnetic (EM) radiation, which means that it does not need a medium to travel, thus it can travel trough space. Visible light looks white but is actually a combination of different colors from red to violet.

In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.

The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.

The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. As shown in the image the order of increasing frequency is : Radio waves, Visible light, X-rays and Gamma rays.
