How did Romer calculate the speed of light?
In the late 19th century, American physicist Edward W. Morley and his colleague Albert A. Michelson conducted a series of experiments to measure the speed of light. However, not until the early 20th century would a more accurate measurement of the speed of light become made. As a result of the work of Dutch physicist Hendrik Lorentz. In addition! his student Pieter Zeeman, using an improved version of Michelson’s interferometer.

Later, in 1926, American physicist Arthur Holly Compton conducted another experiment to measure the speed of light by observing the scattering of X-rays from electrons. Compton’s measurement provided a more accurate value for the speed of light than previous measurements, but it was still not precise enough for many applications.
In 1947, the American physicist Robert W. Wood and his colleague Albert G. Wilson used a microwave interferometer to measure the speed of light with high precision. Their measurement was based on the interference of microwaves passing through a vacuum chamber of known length. This measurement provided a highly accurate value for the speed of light, and subsequent measurements using other methods have confirmed this value to be approximately 299,792,458 meters per second.
It is worth noting that Paul Romer, an American economist and recipient of the Nobel Memorial Prize in Economic Sciences, is not known for calculating the speed of light. Romer is known for his work on endogenous growth theory, which focuses on the role of technological progress in economic growth.
