An improved version of the “extraordinary tabletop speed of light apparatus”
Editor's Note: An improved version of the previously published tabletop speed of light apparatus is presented, in which the amplitude modulation frequency is more than doubled, enabling a reduction in the overall size of the apparatus, while improving the precision of the measured value for c. Detailed construction instructions are provided in supplementary material.
