The splitting up of a beam of white light into its different colours is known as:
Correct answer: D. Dispersion
- A. Refraction
- B. Reflection
- C. Interference
- D. Dispersion
Explanation
Dispersion is the correct answer. It refers to the separation of different colors of light due to variations in their refractive indices. When white light passes through a prism, the different colors are bent by different amounts, resulting in the characteristic spectrum of colors seen in a rainbow. Refraction, Reflection, and Interference do not specifically refer to the splitting of white light into its component colors.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
