Light
White light refers to visible light that contains a mixture of all the colors in the spectrum. It is composed of different wavelengths of light combined together.
A transparent object with flat sides that can separate white light into its component colors by refracting (bending) the different wavelengths.
Spectrum: The range of colors produced when white light is dispersed or separated by a prism, revealing individual bands of colored light.
The distance between two corresponding points on consecutive waves of light. Different wavelengths determine different colors in the visible spectrum.
