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 ?

Which light has the greatest speed?
In a vacuum, all colors of light - as well as other electromagnetic radiation - travel at the same speed, the so-called "speed of light".
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".
What is similar about light waves of different colors?
Light is an electromagnetic wave. it is under the spectrum of electromagnetic waves of range 400nm-750nm. below 400nm are IR radio waves etc. and above 750 are like Gamma Xray etc. Every wavelength has different property and "energy". it effects differently on different type of chemicals , metals etc. So, different colors means different wavelengths and energy. and hence they have different effects.
How can the technique of this experiment be used to determine whether any two different colors of light such as red light and blue light travel at the same speed inside the plastic?
Describe the experiment and its technique for me, and I'm likely to spot it.
Does the speed of light differ?
The speed of light is different in different media; light travels more slowly in water than it does in air, for example.
Is speed related to the color of a light wave?
No. All colors of light travel at the same speed in vacuum. Different colors represent light waves with different wavelengths (frequencies).
What can you say about the speed of the different colors light in air?
I could say that shorter wavelengths move faster, but that would be wrong. The truth is that all wavelengths/colors travel at the same speed.
What color has the maximum velocity?
In empty space, light of different colors moves at the same speed - about 300,000 km/sec.
Does red light travel faster than blue light?
No. All colors travel at the same speed. It is called "the speed of light".
Which light has the greatest speed?
In a vacuum, all colors of light - as well as other electromagnetic radiation - travel at the same speed, the so-called "speed of light".
How fast different colors of light travel through a vacuum?
They all travel through a vacuum at the same speed - The speed of light.
What color of light travels with greatest velocity?
All colors of light travel with the same speed.
Which color moves slowest through the spectrum?
Colors don't "move through the spectrum". Light of different colors has the same speed in a vacuum. In transparent materials such as glass or water, there are slight differences in speed, but that depends on the materal.
Can the speed of light be changed?
no. speed of light is always constant . as long as the light stays in the same medium. the speed is generally slightly different in different media.
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.
