Description

Once the rotary mirror is turning at a high frequency ν, the shift Δx of the image on the scale is observed. In the period

which the light requires to travel to the rotary mirror and back to the end mirror, the rotary mirror turns by the angle

Thus, the image shift is

The velocity of light can then be calculated as

To determine the velocity of light in experiment P5.6.1.1, the image shift is measured as a function of the speed of the mirror.
