No, that number is its speed. You can spot it right away, because "km per sec"
is a unit of speed, not frequency. The number you gave is a useful approximation,
and is within 0.07% of the real number.
-- The speed of light in any medium is the reciprocal of the square root of the product
of the electrostatic permittivity of the medium and its magnetic permeability.
-- In SI units, the electrostatic permittivity of vacuum is 8.85 x 10^-12 farad/meter,
and its magnetic permeability is 1.26 x 10^-6 henry/meter (both rounded).
-- The reciprocal of the square root of the product of those two quantities is (roughly)
300,000 km per second.
That's why.
Its speed is almost 300,000 kilometres per second, so yes, it does
The exact speed of light in a vacuum is 2.99792458 x 108 ms-1 or 2.99792458 x 105 km per second or 299,792,458 meters per second.
The speed of light is not 3000000 km per second so there is no reason for it to be that speed.
176,238,050,200,000,000 miles.
There are approx 9.5 quadrillion metres.
300,000,000
Light travels at 299792458 meters per second in a vacuum.
The speed of waves varies greatly, depending on the type of wave. The fastest waves travel at the speed of light, which is ca. 300 million meters/second.
The light travels at the speed of light which is just under 3 hundred million meters per second
Well, all light travels at well, the speed of light, which is 2.98 *10^8 meters/second.
All electromagnetic waves travel at the same speed, it is known as the speed of light. This number is roughly 300 million meters per second in vacuum, somewhat less in material substances.
Radio waves travel at the speed of light 300 Million meters/second, 300e6 meters/second
Light travels 300,000 km per second, or 300 million meters/second. Convert the 2 hours to seconds, then multiply by 300 million.
X-rays are a kind of electromagnetic radiation - similar to light. They travel at the speed of light through a vacuum - about 300 million meters/second.X-rays are a kind of electromagnetic radiation - similar to light.

In a vacuum, light will travel 299,792,458 meters in one second.
299,792,458 meters/second

The speed of light in vacuum is:186,282 miles per second.299,792,458 meters per second.
Light waves travel fastest through vacuum, at nearly 30 million meters per second. Light travels more slowly through other substances such as air and water, and can be absorbed.
Light travels at 299792458 meters per second in a vacuum.
Light travels at 299792458 meters per second in a vacuum.
It would take you just over 5 years 9 months to travel 56,000,000,000,000 kilometers at the Speed of light, 299,792,458 meters per second.
