When a ray of light is passed through a prism, it splits into his constituent colours. This phenomenon is called:
Dispersion of light
The correct answer is Dispersion of light.
In order of decreasing wavelength (and increasing frequency), they are: Red Orange Yellow Green Blue Indigo Violet This sequence of colours is observed when white light undergoes dispersion. Each colour corresponds to a specific range of wavelengths. The phenomenon of dispersion was famously studied by Sir Isaac Newton, who used prisms to demonstrate that white light is a combination of these various colours. He also showed that these colours could be recombined using another prism to form white light again.
