Question

first?Solution
Galileo is often credited with being the first scientist to try to determine the speed of light. Galileo's experiment was carried out by the Accademia del Cimento of Florence, Italy, in 1667, with the lanterns separated by about one mile, but no delay was observed. The actual delay in this experiment would have been about 11 microseconds. The first quantitative estimate of the speed alight was made in 1676 by Romer.
