What can separate white light into seven colors?
These colors are often observed as light passes through a triangular prism . Upon passage through the prism, the white light is separated into its component colors – red, orange, yellow, green, blue and violet. The separation of visible light into its different colors is known as dispersion.
Does white light have 7 colors?
White light is called as white because it consists of seven colors . The sunlight splits into seven colors namely violet, indigo, blue, green, orange, and red. We usually call it as VIBGYOR. When we mix all these colors we just get one light which is the WHITE light.

Who split white light into colors?
A scientist who did split light by putting a glass prism in a narrow beam of sunlight, actually saw a light that was broken into seven colors by a prism and his name is Isaac Newton . These are important facts to know in regards to prisms. Prisms can separate white light into a group of colors called the spectrum.
Is white all colors combined?
White light is a combination of all colors in the color spectrum . It has all the colors of the rainbow.
