Question

Quizplus · Accepted Answer

The variation of the speed of light in a transparent medium with frequency is called dispersion. This occurs because different frequencies of light travel at slightly different speeds in the medium, leading to the separation of white light into its component colors in a prism, for example. Therefore, choice C is the best answer.
