Is it true that the speed of light in vacuum is the same value regardless of wavelength?

Yes.
No experimental evidence has ever been found that would suggest that any wavelength of light travels at a different speed than any other.
We speak, of course, only about electromagnetic radiation in a vacuum.

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 are wave velocity frequency period and wavelength related?
Wave frequency can be calculated by dividing the speed of the wave (if we're talking about electromagnetic waves in vacuum, that would be the speed of light, c) by wavelength.
Why is the speed of light limited in a vacuum?
The speed of light is not limited in a vacuum - the speed of light is fastest in a vacuum. But that is what Einstein called the "Cosmic Speed Limit" - nothing can move faster than the speed of light in a vacuum, or even quite asfast.
How does the average speed of light glass compare with its speed in a vacuum?
About 2/3 its speed in a vacuum.
What is the speed of light in miles per second in a vacuum?
The speed of light is 186,000 miles per second in a vacuum.
What percentage of the speed of light in vacuum is the speed of light in water?
When light with wavelength of 589 nanometers moves through water at the temperature of 20° C, its speed is 75% of the speed of light in vacuum.
Which travels faster in a vacuum gamma rays or infrared rays?
Neither. In vacuum, all electromagnetic radiation has the same speed, regardless of wavelength. It's the speed we call "the speed of light", but it applies to all of those other electromagnetic phenomena too.
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.
The wavelength of light is defined as?
The speed of light in vacuum is 299 792 458 Metre_per_second
What is the wavelength of an electromagnetic wave that has a frequency of 2.45 109 Hz in a vacuum (The speed of light in a vacuum is 3.00 108 ms.)?
You need to divide the speed of light (in m/s) by the frequency (in Hz, which is equal to 1/s) to get the wavelength (in meters).
What is the radio wave speed range for visible light?
There's no 'range'. The speed of any electromagnetic signal, including light, is 299,792,458 meters (186,282 miles) per second in vacuum, somewhat slower in any material, depending on the material, regardless of wavelength.
An electromagnetic wave in a vacuum has a wavelength of 0.032 m What is its frequency?
Just divide the speed of light (300,000,000 meters/second) by the wavelength.
What is the frequency of light in fused quartz if the wavelength in vacuum is 500nm?
Divide the speed of light in a vacuum (in meters/second) by the wavelength (which you must convert to meters); that will give you the frequency in hertz. The frequency will be the same for different substances.
What is the speed of all electromagnetic radiation?
All electromagnetic radiation, regardless of its wavelength, travels at what is called the "speed of light". In a vacuum, it is measured as299,792,458 meters per second.3.0 x 108 meters per second.186,282 miles per second.Depending on the material and its frequency (or wavelength) it may also be able to travel through other media but at a slower speed than in a vacuum.
How do you know the speed of an electromagnetic wave in a vacuum?
The speed of electromagnetic waves in a vacuum is the same as the speed of light (which is, in itself an electromagnetic wave). It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.
How fast different colors of light travel through a vacuum?
They all travel through a vacuum at the same speed - The speed of light.
The wavelength of a beam of light passing through a vacuum is 420 nanometers. What is the frequency of the light beam?
You need to divide the speed of light by the wavelength. (To have consistent units, you must first either convert the speed of light to nm/second, or convert the wavelength to meters.)
