Yes - all light (and in fact, all electromagnetic radiation) travels at the same speed (about 300 000 km/s). Different coloured light is seen as different colours because it has different wavelengths and frequencies.
The speed of light c, the wavelength of light lambda , and its frequency f are related by the following formula:
c = f x lambda
c is a constant - it never changes. This remarkable fact led Einstein to his theory of Special Relativity.

∙ 12y agoI really doubt this because if speed of light is proportional to energy E=MC^2 than light emitted sun should be more than that of the light coming from bulb or other small source
i am not sure but this is my assumption
INS truth
No, different colors of light travel at slightly different speeds in a vacuum. This phenomenon is called "dispersion" and it is due to the varying wavelengths of different colors.

∙ 7y agoThe speed of light Changes a Little depending on what it's travelling through. Its fastest in vacuum and slower in glass or water.

What color of light travels with greatest velocity?
All colors of light travel at the same speed in a vacuum, which is about 299,792 kilometers per second. This is a fundamental constant in physics known as the speed of light.
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 light has the highest velocity in a vacuum a. red b. ultavilet c. violet d. blue e. green f. all travel at the same velocity?
f. all travel at the same velocity. In a vacuum, all colors of light travel at the same speed, which is approximately 299,792 kilometers per second. This speed is known as the speed of light.
Why do waves of different wavelengths travel at the same speed?
All light travel at the same speed.
How fast different colors of light travel through a vacuum?
All colors of light travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second (186,282 miles per second). This speed is a constant in a vacuum for all wavelengths of light.
Does red light travel faster than blue light?
No. All colors travel at the same speed. It is called "the speed of light".
What color of light travels with greatest velocity?
All colors of light travel at the same speed in a vacuum, which is about 299,792 kilometers per second. This is a fundamental constant in physics known as the speed of light.
Is speed related to the color of a light wave?
No, speed of light is constant in a vacuum at approximately 299,792 kilometers per second. The color of a light wave is determined by its frequency and wavelength, not its speed.
Do infrared waves travel more quickly visible light?
No. All colors of light, and all other forms of electromagnetic radiation, all travel with the same speed.
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".
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 travels most slowly in glass?
Red light travels most slowly in glass because it has the longest wavelength among visible colors, causing it to be refracted the most.
What can you say about the speed of different colors in air?
You can that they're all identical.
Why do waves of different wavelengths travel at the same speed?
All light travel at the same speed.
Does the color of a laser affect the velocity of a light wave projected by the laser?
No, the color of a laser does not affect the velocity of the light wave it emits. The speed of light in a vacuum is a constant value and is not influenced by the color of the light source.
What do all types electromagnetic radiation have in common?
They travel at the speed of light (c = 3*108 m/s)
What is it that all electromagnetic waves do the same?
All electromagnetic waves travel at the same speed in a vacuum -- the speed of light.
