Explain how you can cause light separated by a prism to combine

White light undergoes dispersion when refraction and Snell's law split it into its various constituent colors. What is prism?The only reason white light seems white is because it contains all of the visible colors. Although they are extremely similar, each color's index of refraction in non-vacuous materials is distinct. Each wavelength travels down a different path as a result of these distinctive indices.Sir Isaac Newton discovered that the edges of an image of a heavenly body created by the refraction of white light by a lens are colored. He believed that the colored image was the result of a lens flaw. He carried out another experiment with a prism to look at it more.Therefore, White light undergoes dispersion when refraction and Snell's law split it into its various constituent colors.

When you shine a lite through a prism is reflects out light through all of the edges and causes light separation. Or just simply shine a laser through the edge of a sideways piece of glass.I hope that this was helpful for you.
