How long does it take light to travel 1 meter in a vacuum?
, Physics professor since 1977. The same as the speed of light to travel any other distance. Do you mean, “How long does it take light to go 1 meter?” If so, the answer is 3.335641 nanoseconds.
What is the distance that light travels through a vacuum in 1 299792458?
Meter Defined by Speed of Light: The meter is defined to be the distance that light travels in 1/299,792,458 of a second in a vacuum.
What is the distance Travelled by light through vaccum in 1 second?
The distance travelled by light in one second is 299,792,458 m. This is a large quantity and cannot be used as a base unit.
Why is the speed of light 299792458?
The speed of light is 299 792 458 m/s because people used to define one meter as 1/40,000,000 of the Earth’s meridian – so that the circumference of the Earth was 40,000 kilometers.
How long does it take light to travel 1 foot?
It is approximately true that light travels one foot in one nanosecond – so without much math – about five and a half nanoseconds.
What is the distance that light travels through a vacuum in 1 299792458 of a second group of answer choices centimeter kilometer meter centimeter?
One kilometer is equal to 1,000 meters, which are defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.
What is defined as the distance the light travels in a vacuum in?
It’s official now. The speed of light is exactly 299,762,458 meters per second. The meter now is officially defined as the distance light travels, in vacuum, in the incredibly short time span of one second divided by 299,762,458.
Why is Metre defined as distance?
Since 1983, the metre has been internationally defined as the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second.
Why is a Metre defined in terms of the speed of light?
Originally Answered: Why is a metre defined interms of the speed of light? Because it is possible to define it far more precisely by basing it on a known universal physical constant. In this way it does not depend on any standard artifact (object) and can be independently verified anywhere.
