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.
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.
Does speed increases as a wavelength increases?
No, speed is not directly related to wavelength in the context of light. In a vacuum, all wavelengths of light travel at the speed of light (approximately 299,792,458 meters per second). However, in a medium such as glass or water, different wavelengths of light travel at different speeds due to their interaction with the medium.
Is it true that a vacuum different color of light travel at different speeds?
In a vacuum, all colors of light travel at the same speed, which is approximately 299,792 kilometers per second (186,282 miles per second). This speed is known as the speed of light and is a universal constant that does not change based on the color of light.
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".
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 ?
Are the iron losses constant at all speeds?
Iron losse are constant at all different levels of speed
Is speed of violet light different from red light in glass?
Yes, the speed of violet light in glass is higher than the speed of red light. This is due to the phenomenon of dispersion, where different colors of light are refracted at different angles as they pass through a medium, causing them to travel at different speeds.
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".
Does light always travel at the same speed?
The speed of light is always the same as long as it's traveling through the same medium. But its speed is different in different media, and those are all less than its speed in vacuum.
What is the landing speed of light aeroplane?
Landing speeds of all aircaft differ. Most light aircraft will land around 45-60 mph.
