What is the speed of light squared?

Answer 1

(c0) = 29 979 245 800.00 019 centimeters per second (cm/sec).

. .

Lightning's maximum speed is just short of

30 centimeters per one-million-th of a second.

Answer 2

Light travels at the speed of 186282 miles per sec. According to Einstein it is impossible to go faster or as fast as light because it requires an infinite mass. Right now Einsteins word is law because there has been nothing to disprove him.

Answer 3

The square of the speed of light is the speed of light multiplied by itself. The number you get from such a calculation depends on what units you use, but in most reasonable units that number is very large. Scientists generally measure speed in meters per second, so that is what we will use here. The speed of light is approximately 300,000,000 (300 million) m/s. Squaring that we get 90,000,000,000,000,000 (90 quadrillion) (m/s)^2.

Answer 4

Rounded off, it is 300,000 km/second. This is normally "close enough".

To be more precise, the speed of light in a vacuum (which is normally abbreviated as "c") is 299,792,458 meters per second.
3.0 x 10^5 km/h

Answer 5

c = 299,792,458 meters per second

c2 = 8.9876 x 1016 meters2 per second2


or, for purposes of conversation:

=> 90 billion kilometers2 per second2

=> 34.7 billion miles2 per second2

Note: These units have no physical significance. They're only useful if you're on the way
to calculating the kinetic energy of something, and then you wouldn't be up around the
speed of light.

Answer 6

In a vacuum, light travels 299,792,458 meters per second.

To view this value in terms of kilometers per second, merely divide the value by 1000 (since 1km = 1000 m)

Therefore, light travels at 299,792.458 kilometers per second.

Answer 7

The speed of light is 300,000 km/sec. Multiply that by 60 (seconds/minute) to get the speed in km/minute.

========================

Another angle:

The speed of light is constant, as long as it keeps moving through the same stuff.

So its speed at any time is the same as it was or will be at any other time.

That could be any time in one minute, in a microsecond, or in 479 days.

Answer 8

299,792,458 meters per second (in a vacuum). The speed of light in other media is lower, which is what causes refraction in air or water.

Answer 9

The exact value of the speed of light as decided by the 17th CGPM is 299,792,458 ms-1.

Answer 10

Light travels in a pure vacuum at 299,792,458 km per second.
