Monica Rambeau form of energy within the electromagnetic spectrum. Among the many energy forms she has assumed and is able to control are cosmic rays, gamma rays, X-rays, ultraviolet radiation, visible light, electricity, infrared radiation, microwaves, radio waves, and neutrinos. By assuming an energy-form, she gains all of that energy's properties. She is invisible and intangible in many of her energy forms (the most frequent exception being visible light), and is capable of flight in all her energy forms (reaching velocities up to and including light speed). She also has the ability to project these energies from her body while she is
Umkehr effect Umkehr effect The Umkehr is the time variation of the ratio of the scattered intensity at two different wavelengths. The word means 'reversal' in German. The Umkehr effect is observed when measurements are made with ultraviolet spectrophotometer of the ratio of the zenith sky light intensities of two wavelengths in the solar ultraviolet when the sun is near the horizon. The shorter of two wavelengths (intensity "I") is strongly absorbed and other (intensity "I' ") is weakly absorbed. If the value of log("I"/"I' ") is plotted against the sun's zenith angle, it is observed that this log-intensity ratio decreases as
