Light has seven colors. What is the way to separate colors?

Light can be separated into its constituent colors using a prism (Option A). This process, known as dispersion, occurs when white light passes through a prism and is refracted at different angles depending on its wavelength. As a result, the light is spread out into a spectrum of colors, from red to violet. This principle was first demonstrated by Sir Isaac Newton in the 17th century, showing that white light is composed of various colors that can be separated and observed individually. Besides prisms, colors can also be separated using filters that transmit certain wavelengths of light while absorbing others, or through other optical devices and techniques. Understanding how light can be separated into its component colors is fundamental in fields such as optics, spectroscopy, and photography, where the analysis and manipulation of light wavelengths are essential for scientific research, color production, and technological applications.
