¶ The Kramer Effect
The Kramer Effect, coined by Purgatorian scientists studying the effects of anomaly on electromagnetic waves, is an anomalous effect exhibited on all photons and tachyons passing through anomalous areas. The Kramer Effect observes that photons passing from an area into an area that has a different ECF will be diffracted and scattered, changing wavelength and thus color. This effect becomes more apparent the greater the cuil difference the light passes through and the quicker that cuil difference is. The effect is barely noticeable to the eye when passing into most high ECF areas, but areas that have a very defined border in which the high ECF begins will appear to have a prismatic 'membrane' of multicolored light. The places this effect is extremely noticeable are hyperlanes, which accounts for the prismatic membrane that makes up hyperlane borders.
The Kramer Effect can become a problem when attempting to communicate between areas of differing ECF, as it can cause radio waves to diffract and become incoherent if the difference is large enough. It even affects tachyons, though to a lesser extent. Transmissions become incoherent at an ECF difference of around 10‽.
