Question

Quizplus · Accepted Answer

In glass, red light travels faster than blue or yellow light. This is because glass is a dispersive medium, meaning it slows down different colors of light at different rates due to their wavelengths. Red light, having a longer wavelength, is less slowed down compared to blue or yellow light, which have shorter wavelengths.
