LCP-18 Apparatus for Measuring Speed of Light

Short Description:

The accurate determination of the speed of light is of extraordinary significance. This instrument cleverly uses the differential frequency phase detection method to measure the speed of light, and designs a reflector to increase the effective light range and achieve short distance measurement. The experiment can deepen the perceptual understanding of the speed of light propagation, while understanding the modulation and differential frequency techniques.

LCP-18 Apparatus for Measuring Speed of Light

The propagation speed of light in vacuum is an extremely important fundamental physical quantity, and many physical concepts and quantities are related to it.

Due to their close relationship, measuring the speed of light is a very important topic in physics. The purpose of this experiment is to determine the speed of light by measuring the wavelength and frequency of the light beat, and to master the principle and experimental method of measuring the speed of light using the light beat frequency method.

Experiment

Measuring the velocity of light in air using the light photography method

THERE IS ALSO A PHASE METHOD MEASUREING SPEED OF LIGHT MODEL LCP-18A
