Gravity and Time Dilation (クリ)
There are two mirrors. One is on the ground, one is 22.6m above. These are facing each other. A laser beam is emitted downward from the left end of the upper mirror, forming letter W, and reaches the upper right (beam is in vacuum). Frequency at five points will be the same. There will be no time dilation due to difference of gravity.
Note) A few translations say that, when the distance between two points on the light path remains the same, the frequency of two points are the same (assuming frequency of the light source is constant).
