Apparatus for Measuring Speed of Light Experiment

This apparatus is designed to measure the speed of light using the light modulation (beat frequency) method. It enables students to determine the velocity of light in air by measuring the wavelength and modulation frequency of the light signal, providing a practical understanding of one of the most important fundamental physical constants. A phase-method version is also available for advanced speed of light measurements. Manufactured by Atico Exports.
