Web14. jan 2024 · The terms redshift and blueshift apply to any part of the electromagnetic spectrum, including radio waves, infrared, ultraviolet, X-rays and gamma rays. So, if radio waves are shifted into the... Web1. feb 2024 · The LPI can be tested using typical gravitational redshift experiments, which measure the frequency or wavelength shift z = Δ ν ν between two indistinguishable frequency standards placed at different heights of a static gravitational field. Based on EEP prediction, the shift for clocks at rest is given by Eq.
