In the Fizeau experiment on measurement of the velocity of light the distance between the gear wheel and the mirror is `l = 7.0 km`, the number of teeth is `z = 720`. Two successive disappearances of light are observed at the folllowing rotation velocities of the wheel: `n_(1) = 283rps` and `n_(2) = 313` rps. Find the velocity of light.

In a Michelson experiment for measuring speed of light, the distance travelled by light between two reflections from the rotating mirror is 4.8 km. The rotating mirror has a shape of a regular octagon. At what minimum angular speed of the mirror (other than zero) the image is formed at the position where a non rotating mirror forms it ?
