ProduktbeskrivningSpeed of Light Meter (230 V, 50/60 Hz)
Equipment set for determining the speed of light thanks to electronic run-time measurement.
Comprises a compact housing containing a transmitter emitting short LED pulses, a photo receiver and a calibrated, oscillating quartz generator producing chronologically precise square-wave pulses. Emitted light pulses are returned by an internal reflector and by a triple-prism reflector placed a long distance from the light source. The returning light signals are then superimposed on the original signal. A dual-channel oscilloscope is used to measure the time difference between the two signals. The speed of light can be calculated from this difference and the distance to the triple-prism reflector.
The triple-prism reflector can be installed by eye without the need for complex adjustments
