How light speed measured?
Answers
Answer:
Nowadays, using oscilloscopes with time resolutions of less than one nanosecond, the speed of light can be directly measured by timing the delay of a light pulse from a laser or an LED reflected from a mirror.
One light year: 1.0 year
Distance: Time
From geostationary orbit to Earth: 119 ms
One foot: 1.0 ns
