Question

How far does a beam of light travel in 1 ns?

Short answer

Answer: A beam of light travels approximately 0.2998 meters in 1 nanosecond.

Step-by-step solution

Convert time from nanoseconds to seconds

To convert 1 nanosecond to seconds, we can use the conversion factor 1 second = 1 x 10^9 nanoseconds. Therefore, 1 ns = 1/(10^9) seconds.

Apply the distance formula

Now we can use the distance formula with the speed of light (2.998 x 10^8 m/s) and the converted time value (1/(10^9) seconds). So, distance = (2.998 x 10^8 m/s) x (1/(10^9) s).

Calculate the distance

Multiplying the speed of light by the time value, we get distance = (2.998 x 10^8 m/s) x (1/(10^9) s) = 0.2998 m. Hence, a beam of light travels approximately 0.2998 meters in 1 nanosecond.
