# How far does light travel in 1 nano second?

## How far does light travel in 1 nano second?

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.
