Measurement of the Speed of Light with a Pulsed Laser
... The apparatus used here replaces the persons used by Galileo with electronic circuits, which have much more rapid response times that can be much more precisely measured. The flash of light is created by a pulsed laser diode, a device very similar to a laser pointer, except this laser is switched on ...
