My understanding of how interferometers work is that they detect gravitational waves because they alter the distance between two mirrors as they pass through. They do this by using the wavelength of a laser beam passing through this space.
However, shouldn't this always fail to detect anything, because the wave would always make the same fractional alteration to the photon wavelength as it does to the distance the light has to travel?
Why/how does this work?
thanks.
