... The basic optical configuration is a power-recycled and signal-recycled Michelson interferometer with Fabry-Perot "transducers" in the arms. Using the initial LIGO design as a point of departure, this requires the addition of a signal-recycling mirror at the output "dark" port, and changes in the in ...

The Virgo interferometer runs laser light back and forth inside two
... Even though Virgo has less reach than LIGO, having a third machine will help in several ways. Interferometers are not equally sensitive in all directions, and have blind spots. If the waves come from a direction for which LIGO is relatively ineffective, Virgo could add key information about the even ...

P1.4 to 1.5: Generating Electricity and Waves
... a) If a wave source is moving relative to an observer there will be a change in the observed wavelength and frequency. This is known as the Doppler effect. b) There is an observed increase in the wavelength of light from most distant galaxies. The further away the galaxies are, the faster they are ...
