Question

Quizplus · Accepted Answer

In a vacuum, all colors of light travel at the same speed, which is the speed of light (299,792,458 meters per second or 186,282 miles per second). This is a fundamental principle of physics known as the universality of the speed of light. However, in a transparent medium such as glass or water, the speed of light can vary depending on the color of the light. This is due to the interaction between light and the atoms or molecules in the medium, which affects the light's frequency and wavelength.
