speed of light is always the same, regardless of frequency/colour.
The speed of light in vacuum is defined to be exactly 299,792,458 metres per second.
They travel to the speed of light? to it? and where exactly is the speed of light?
Since light is made of light, whatever speed it goes at is what we call the speed of light. So we'll always see light moving at exactly the speed of light, at least in that particular medium.
"c" in this case means the speed of light in a vacuum. This is approximately equal to 300,000 km per second.
the speed of light
Nothing is faster than the speed of light.
The speed of light in a vacuum has been defined as exactly 299,792,458 meters per second.
The speed of light is a constant, C= 300,000 km per second.
Because they are light.
They are equal.
Exactly 1.000 year.
The speed of light is equal to 1 unit of c, where c is the speed of light in a vacuum, approximately 299,792 kilometers per second.
