A serious, but very uncommon side effect of IL-2 in high doses is capillary leak syndrome or vascular leak syndrome. Capillary leak syndrome is a potentially serious disease in which fluids within the vascular system (veins and capillaries) leaks into the tissue outside the bloodstream.
The electromagnetic spectrum runs from radio waves (the longest wavelength) to gamma waves (the shortest wavelength). In increasing wavelength order, the electromagnetic spectrum is: radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays. In the visible spectrum, violet light has the shortest wavelength.
This means that it is correct to talk about the energy of an X-ray or the wavelength of a microwave or the frequency of a radio wave. The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.
