As long as it stays in one medium (substance), the speed of all wavelengths of
visible light is very close to the same number. It only changes when the light
crosses into a different substance, like going from air into water, or from glass
into jello.

Speed of red light and blue light in a vacuum?
In a vacuum the speed of red and blue light are the same as all light, 300,000,000m/s. Their frequency and wavelength will be different but the speed remains the same.
How does the average speed of light in glass compass with its speed in a vacuum?
There are several different types of glass, and light has a somewhat different speed in each of them. On the average, the speed of light across all typical types of glass is in the neighborhood of 2/3 its speed in vacuum, or around 200,000 km/sec .
Different kinds of energy waves that move at the speed of light in a vacuum make up the?
In any substance, all electromagnetic waves travel at the same speed that light travels through that substance.
How would you find the average speed if the person went 3 different speeds in a length of 5 hours?
You need to work out how far they travelled at each speed (distance = speed x time) then add all three distances together to get a total and divide by 5 hours to get the average speed
How long would it take for speed of light to travel a quintillion miles?
The speed of light doesn't travel at all. It just lays there, typicallyon a printed page in a book.If an object is traveling at the speed of light, however, then it's acompletely different story. Such an object would cover 1 quintillionmiles in only 170,108 years (rounded).
Is Long wavelength visible light have a speed that is slower than short wavelength light which one?
In a vacum all wavelengths of light have the same speed of 3 x 10^8 m/s. However, in a medium like glass or water the speeds of light are different for different wavelengths and the longer wavelength has a higher speed then the shorter wavelength. Although both speeds are slower then their speeds in a vacum.
Is it true that a vacuum different color of light travel at different speeds?
No, that is not true. In a vacuum, all electromagnetic waves travel at the same speed.
Why do crystals make everything look colorful when you look in to it?
It's because different colours of light traverse at different speeds, when they're all traversing at the same speed the light colour is, 'transparent' light traverses at different speeds through crystals / glass due to refraction.
What was the speed of an airplane in 1950?
Airplanes all have different speeds.
Is it true that different kinds of E-M waves travel through space at different speeds?
No. All E-M waves travel through space at the same speed, known as the"Speed of Light".
How do the speeds of various electromagnetic waves compare?
They all move at the speed of light. Wavelength varies, but the speed is the same.
How the speed of visible light compare with gamma rays when both speeds are measured in a vacuum?
Visible light and gamma rays are different parts of the full spectrum of light. Since they are really both just light, they travel at the same speed, the speed of light. 186,000 miles per second.
Why is the speed of the different colors of light in air the same?
All wavelengths are the same physical phenomenon ... electromagnetic radiation ... whose speed depends on the electrical properties of the medium in which it is propagating. Why would you think that they should travel at different speeds ?
What is the Speed of light travelling through transparent material?
Translucent materials allow all the light to pass through but the light does not form images or obey Snell's law.
Are the iron losses constant at all speeds?
Iron losse are constant at all different levels of speed
Why white light colours have different speeds according to their frequencies but not the other electromagnetic waves while all have the same speed of light?
Answer: The white colors have different speeds and not other electromagnetic waves because they are not usually consisted by more than one colors like the white colors. Answer: You are really confusing two different things. (1) In a vacuum, all electromagnetic waves travel at the same speed. That includes light of different colors. They all travel at the so-called "speed of light" - without further qualification, this term means "the speed of all electromagnetic waves in a vacuum", and this speed is approximately 300,000 km/sec. (2) In materials other than a vacuum (empty space), electromagnetic waves get slowed down - and the amount by which they slow down depends on the frequency. Thus, not only light of different colors will be slowed down by different amounts, but also radio waves, ultraviolet rays, etc., if they are able to pass through a material at all. For more information, do some reading - for example, on the Wikipedia - on "index of refraction", and on "speed of light".
is it true that All light waves travel at different speeds in different materials?
never mind I figured it out. it is true
