Answer. 【Tips】 <br />The principle used in the problem-solving process is called dispersion of light. A prism uses this technique to separate white light into a spectrum of colors by refracting (bending) different frequencies of light at different angles.
A dispersive prism can be used to break white light up into its constituent spectral colors (the colors of the rainbow) to form a spectrum as described in the following section. Other types of prisms noted below can be used to reflect light, or to split light into components with different polarizations .
A prism is a piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light. A prism can separate white light into its constituent colours, called a spectrum, by refracting each wavelength differently.
Upon passage through the prism, the white light is separated into its component colors - red, orange, yellow, green, blue and violet. The separation of visible light into its different colors is known as dispersion.
Learn how a prism, a transparent object, can separate white light into its component colors by changing their directions. See examples of how different objects affect the color of light and how we see colors.
When white light is passed through a glass prism it splits into its spectrum of colours (in order violet, indigo, blue, green, yellow, orange and red) and this process of white light splitting into its constituent colours is termed as dispersion.
Learn how white light is separated into its colors by a prism due to refraction and Snell's law. Explore the applications and natural phenomena of dispersion, such as rainbows and the color of the sky.
