Features:
The fact that light is propagated at a finite speed can be demonstrated by a simple transit time measurement. This is achieved by using very short light pulses of only a few nanoseconds duration and determining the time for them to travel out and back over a distance of several metres, which is measured by an oscilloscope. From the transit time and the distance from the transmitter to a triple-prism reflector one can calculate the velocity of light.
