When light passes through a medium boundary - from air to glass, for example - and if it strikes that boundary at an angle of incidence that is less than 90o, (that is, the light does not strike perpendicular to the boundary), then the light diffracts, or bends, or changes direction slightly.
.
The angle of diffraction - the amount the light bends - depends upon two things: the difference in the diffraction index between the two mediums, and the wavelength. The diffraction angle is proportionate to the wavelength - meaning that the longer the wavelength of the light, the greater angle the light bends as it crosses the medium boundary.
.
Since red light has a longer wavelength than blue light does, red light diffracts, or bends, at a greater angle than blue light bends when they both strike the prism at the same angle of incidence. White light contains all the colors of the rainbow. So when white light strikes a prism, the red component of the white light bends at a greater angle than the blue light, and so we see a fanning out of light - red at one side of the fan, blue at the other side.
A prism is a piece of glass that can break white light into the colors of the spectrum (red, orange, yellow, green, blue, indigo, violet) through refraction.
A prism refracts white light, which is composed of different colors with different wavelengths, causing them to bend at different angles. This separation of colors is called dispersion, and it results in the formation of a rainbow when the dispersed light is observed.
Sir Isaac Newton is credited with the first explanation of how a prism is used to break white light into a rainbow of colors. In 1666, Newton conducted experiments using prisms to demonstrate that white light is made up of a spectrum of colors.
The separation of white light into different colors by a prism is called dispersion.
Prism doesn't add colors to white light, it just dissipate the all colors of white light into different direction. White light contains all seven colors in it. So don't be confused in the addition of colors into white light or dissipation of all colors, containing in white light.

Breaking of white lights means dispersion of light in which the white light or the visible light splits into 7 colors. Many tools may be used to break up the white light but among them one of them is Prism. It can break up the white lights into 7 colors. Keep a white paper in front of the prism and the prism in the sun due to which the sunlight coming from the sun passes through the prism and the white breaks up into 7 colors due to change in velocity of the different invisible lights inside the white or the visible light. Other tools like plastic scale or ruler also can be used to break up the white light. Thank you
Isaac Newton used a triangular prism to separate white light into its spectrum of colors. When white light passes through the prism, the different wavelengths of light are refracted by different angles, causing them to spread out and create the rainbow of colors.
They can use a kind of glass/cristal named Prisma

White light can be separated into different colors using a prism, a process known as dispersion. When white light passes through a prism, it splits into a rainbow spectrum of colors. This supports the idea that white light is made up of all the colors of the spectrum. Additionally, when all colors of light are combined, they create white light.
A Prism can be used to break light up into its constituent spectral colors.
It splits white light up into the colors of the visible spectrum, but if the colors go through another prism, they turn into white light again.
A prisma prismA prism separates light into the colors of the rainbow...a good way to remember the colors in their proper order is Roy G. Biv = red, orange, yellow, green, blue, indigo, violet.prismA prism is what Newton used.A 60/60/60 Glass triangular prism.Prism, or a diffraction grating.A prism is a device that separates white light into the different coloursThe device that is used to separate white light into colors is called a prism. It uses a property of light called refraction. Refraction works because as light enters the prism, the speed slows down. When the light exits the prism, the change in speed causes the white light to break into the colors that make it up.
