The distance between the two mirrors is 1 km and the mirror is rotating at 750 rev/s. Calculate the velocity of light.
A beam of light is reflected by a rotating mirror onto a fixed mirror which sends back to the rotating mirror from which it is reflected and then makes an angle of 3.6° with the original direction. The distance between the two mirrors is 1 km and the mirror is rotating at 750 rev/s. Calculate the velocity of light.

In Michelson’s experiment for measuring the speed of the light, the distance traveled by light between two reflections from the rotating mirror is 4.8 km. The rotating mirror has the shape of a regular octagon. At what frequency of rotation of mirror the image is formed at the position where non-rotating mirrors form it?

The beam of light after the reflection at a plane mirror, rotating 2000 times per minute, passes to a distant reflector. it returns to the rotating mirror from which it is reflected to make an angle of 1° with its original direction. If the distance between the mirror is 6250 m, calculate the velocity of the light.
