Question

How much distance light travel in each Nanosecond?????


hint, A nanosecond is an SI unit of time equal to one billionth of a second, that is, ​¹⁄₁ ₀₀₀ ₀₀₀ ₀₀₀ of a second.​

Answer 1

Answer:

One light-nanosecond is almost 300 millimetres (299.8 mm, 5 mm less than one foot), which limits the speed of data transfer between different parts of a large computer. One light-microsecond is about 300 metres. The mean distance, over land, between opposite sides of the Earth is 66.8 light-milliseconds.
