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.
All light travel at the same speed.
They all travel through a vacuum at the same speed - The speed of light.
They travel at the speed of light (c = 3*108 m/s)
no, light is faster
All electromagnetic waves travel at the same speed in a vacuum -- the speed of light.
In a vacuum, light always travels at the same speed, about 300 000 kilometers per second.
Hypothetically, yes. The speed of light is relative to the observer, so no matter how fast one is traveling, light always appears to travel at the same speed.
All light travel at the same speed.
They all travel through a vacuum at the same speed - The speed of light.
No. All colors travel at the same speed. It is called "the speed of light".
They travel at the speed of light (c = 3*108 m/s)
Gamma rays travel exactly the speed of light because gamma rays are light
no, light is faster
No. Both travel at exactly the same speed. The speed of light.
No, light in a medium will travel at a slower speed.
All electromagnetic waves travel at the same speed in a vacuum -- the speed of light.
Light always travels at the same speed, the speed of light. At least in vacuum. In a medium light will travel at a slower pace, and the speed decrease is dependent on the color (wavelength) of the light. This is because the refractive index (which determines how fast light can travel through a medium) is color dependent.
