dispersion of white light into its constituent colours
That white light is made up of all the colours of light mixed together.

Isaac Newton's triangular prism was likely made of glass, a common material for prisms during his time due to its transparency and ability to refract light.
Newton explained his theory
When the colors formed by a prism is made to pass through a second prism, it results in producing white light. Newton's experiment demonstrated in this method is recombination of light. Conversely dispersion can be demonstrated with the help of a single prism.
he used a prism?
a prism, and the telescope
Newton's prism experiment proved that white light is composed of different colors (spectrum) and that these colors can be separated by passing through a prism. Additionally, it demonstrated that light can be refracted into its various wavelengths, creating a rainbow effect.
Sir Isaac Newton is the scientist who used a prism to study light. He discovered that white light is composed of a spectrum of colors when passed through a prism, leading to his development of the theory of color.
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.
