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
Photoelectric effect certain threshold frequency (typically visible light for alkali metals, near ultraviolet for other metals, and extreme ultraviolet for non-metals), the radiation is absorbed and electrons are emitted. Light, and especially ultra-violet light, discharges negatively electrified bodies with the production of rays of the same nature as cathode rays. Under certain circumstances it can directly ionize gases. The first of these phenomena was discovered by Hertz and Hallwachs in 1887. The second was announced first by Philipp Lenard in 1900. The ultra-violet light to produce these effects may be obtained from an arc lamp, or by burning magnesium, or by sparking
