How far does light travel in 1 nano second?
about 300,000 kilometers
One way to think of it, Kaertner says, is in terms of how far light can move in a given amount of time. Light travels about 300,000 kilometers (or 186,000 miles) in one second. That means it goes about 30 centimeters — about one foot — in one nanosecond.
How far does light travel in 1 micro second?
Answer and Explanation: Light travels 300,000 meters in 1 millisecond. 1 millisecond is 1/1000 of a second. 300,000 meters is 300 kilometers, which is just over 186 miles.
How fast is nano second?
A nanosecond (ns) is an SI unit of time equal to one billionth of a second, that is, 1⁄1 000 000 000 of a second, or 10−9 seconds. The term combines the prefix nano- with the basic unit for one-sixtieth of a minute. A nanosecond is equal to 1000 picoseconds or 1⁄1000 microsecond.
How far does light travel per second?
Light traveling through a vacuum moves at exactly 299,792,458 meters (983,571,056 feet) per second. That’s about 186,282 miles per second — a universal constant known in equations and in shorthand as “c,” or the speed of light.
What is the shortest second?
zeptosecond
A zeptosecond is a trillionth of a billionth of a second, or a decimal point followed by 20 zeroes and a 1. Previously, researchers had dipped into the realm of zeptoseconds; in 2016, researchers reporting in the journal Nature Physics used lasers to measure time in increments down to 850 zeptoseconds.
What is faster than seconds?
A millisecond (from milli- and second; symbol: ms) is a thousandth (0.001 or 10−3 or 1/1000) of a second. A unit of 10 milliseconds may be called a centisecond, and one of 100 milliseconds a decisecond, but these names are rarely used.
What is the fastest second?
An attosecond is 1×10−18 of a second (one quintillionth of a second). For context, an attosecond is to a second what a second is to about 31.71 billion years. The word “attosecond” is formed by the prefix atto and the unit second.
How much does light travel in a nanosecond?
Related Questions More Answers Below. Light travels at 299,792,458 meters per second and a nanosecond is a billionth of a second so in one nanosecond light travels about 0.3 meters or about 0.98 feet per nanosecond.
Which is faster one foot or one nanosecond?
One foot is 12 inches. Light travels approximately one foot in one nanosecond.
What is the definition of the speed of light?
The definition of the speed of light is: 299,792,458 meters per second and one second equals 109nanoseconds. Set it up like this: (299,792,458 m s¯1) x (1 s/109ns)
How big is one meter in nanoseconds?
One meter is defined as 39.37 inches. (0.299792458 m ns¯1) x (39.37 in m¯1) = 11.8 inches per nanosecond. One foot is 12 inches. Light travels approximately one foot in one nanosecond.
