By Dispersion Of light (We call the phenomenon of spiliting of white light into 7 colours as dispersion of light.)..........
You Can use Prism.....
Because god has made it with different colors
Light is made up of different colors that are a part of the electromagnetic spectrum. Different colors have different wavelengths, and when white light is separated, it can be seen as a spectrum of colors ranging from red to violet.
When you mix the secondary colors of light (cyan, magenta, yellow), you get white light. This mixing process is known as additive color mixing, where the combination of different colored lights results in a lighter overall color.
Green and red made by oxygen atoms Blue and Purple made by nitrogen atoms The different colors appear in a different altitude
Newton demonstrated this with his prism.
A prism can change white light to a rainbow because white light is made up of different colors, each with a different wavelength. When white light enters a prism, the different colors of light are refracted by different amounts due to their unique wavelengths, causing them to spread out and form a spectrum of colors called a rainbow.
White light is made up of different colors. When white light enters water (like moisture in the air) it is bent (refracted). However the different colors are bent (refracted) by different amounts. So this different amount of bending has the effect of separating the white light into its colors and we see this as a rainbow.lalalalalalalalalalalalalalalalalalalawwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww
When Newton passed white light through a prism, he observed the light being separated into a spectrum of colors. This demonstrated that white light is made up of a mixture of different colors with different wavelengths.
One way to prove that white light contains a mixture of different colors is by passing it through a prism. The prism will refract the white light into a spectrum of colors, known as a rainbow, showing that white light is composed of various colors. This experiment demonstrates that white light is made up of a combination of different wavelengths.
White light is made up of many colors because it is a combination of different wavelengths of light. When white light passes through a prism, the different wavelengths are refracted at different angles, separating the colors and creating a spectrum. Each color corresponds to a different wavelength within the visible light spectrum.
When you shine yellow, magenta, and cyan lights onto a white screen at the same spot, they combine to produce white light. This is because yellow is made of red and green light, magenta is made of red and blue light, and cyan is made of green and blue light. When all three colors overlap, the red, green, and blue components mix together, resulting in white. This additive color mixing demonstrates how different colors of light can combine to create a new color.
There are two ways of doing this: 1) use a prism to split white light into different colors - see the related link below. 2) use a spinning disk to merge colors to make white - see the related link below.
