Red light and violet light travel at the same speed in a vacuum, however, they travel at different speeds relative to each other when traveling through any medium other than a vacuum.
In most media, violet light has a higher index of refraction (usually denoted with the letter n) than red light. The higher the index of refraction, the slower the light goes compared to its speed in a vacuum. This relationship is governed by the following equation: v = c/n where v is the speed of light in a particular medium, n is the index of refraction of light in that medium, and c is the speed of light in a vacuum. Since red light has a smaller n than violet light in most media, red light travels faster than violet light in most media.
The index of refraction is determined by solving Maxwell's equations for a particular frequency and a particular medium using specific boundary conditions.

What else can I help you with?
What is faster red or violet light?
Violet light is faster than red light because violet light has a shorter wavelength and higher frequency, allowing it to travel faster through a medium.
What Violet is refracted the?
Violet light is refracted when it passes through a medium with a different optical density, causing it to change direction. This change in direction is due to the different speeds at which violet light travels in different mediums, such as air, water, or glass.
What travels more slowly in glass red light or violet?
Red light travels more slowly in glass than violet light. This is because the speed of light in a medium is inversely proportional to its wavelength, and red light has a longer wavelength compared to violet light.
Which light travels faster in an optical fiber - ultraviolet or infrared?
Neither. All electromagnetic radiation (light) travels at a constant speed through whatever medium it encounters. Light in a vacuum, for instance, is about 186,282 miles per second; whereas in a fiber optic cable it chugs along at only 115,000 miles per second.*What distinguishes ultraviolet from infrared is the amount of energy associated with it, reflected in its frequency. Assuming that a particular cable is transparent to both forms of radiation (which may or may not actually be the case, as another name for infrared radiation is heat) it is likely that the ultraviolet energy would travel farther before its signal would need to be reboosted.*The speed of light through a medium is proportional to its index of refraction. The index of refraction of fiber optic cable is about 1.62; this means that light travels through it only about 60% as fast as it does through outer space.
What is it called when energy travels through empty space?
It is called electromagnetic radiation. This type of energy consists of electric and magnetic fields that can propagate through a vacuum without requiring a medium. Examples include light, radio waves, and X-rays.
What is faster red or violet light?
Violet light is faster than red light because violet light has a shorter wavelength and higher frequency, allowing it to travel faster through a medium.
The colour of light which travels through glass with the minimum speed is?
The color of light that travels through glass with the minimum speed is violet. This is because the speed of light in any medium, including glass, is dependent on the medium's refractive index, with shorter wavelengths like violet experiencing a slower speed.
What refracts more red or violet?
Violet light refracts more than red light because violet light has a shorter wavelength and higher frequency, causing it to bend more when passing through a medium. This is known as dispersion, where different colors of light are separated due to their different wavelengths.
What Violet is refracted the?
Violet light is refracted when it passes through a medium with a different optical density, causing it to change direction. This change in direction is due to the different speeds at which violet light travels in different mediums, such as air, water, or glass.
Which color of light travels fastest through a telescope lens?
All colors of light travel at the same speed in a vacuum, including through a telescope lens. The speed of light is determined by the medium it travels through; in air or a lens, all colors of light travel at the same speed.
What travels more slowly in glass red light or violet?
Red light travels more slowly in glass than violet light. This is because the speed of light in a medium is inversely proportional to its wavelength, and red light has a longer wavelength compared to violet light.
Which color refracts most?
Violet because it has a shorter wavelength and higher frequency

How many pages does Through Violet Eyes have?
Through Violet Eyes has 368 pages.
When white light travels through a glass prism which colour is refracted through the largest angle?
Violet light is refracted through the largest angle when white light passes through a glass prism because it has the shortest wavelength of all the colors in the visible spectrum.
Which colour is bent most by a prism in the spectrum?
Violet light is bent the most by a prism in the visible spectrum. This is because violet light has a shorter wavelength compared to the other colors in the spectrum, causing it to refract more when passing through a medium like a prism.
