INDIVIDUAL READY RESERVE. The Navy Individual Ready Reserve (IRR) is a force that consists of personnel who must fulfill their MSO under 10 U.S.C., 651, members fulfilling a service obligation incurred via contract, and those who have fulfilled their MSO but voluntarily remain in the IRR.
Electromagnetic radiation (EM radiation or EMR) is the radiant energy released by certain electromagnetic processes. Visible light is one type of electromagnetic radiation, other familiar forms are invisible electromagnetic radiations such as radio waves, infrared light and X rays.lassically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields that propagate at the speed of light through a vacuum.
Blackbody radiation or cavity radiation refers to an object or system which absorbs all radiation incident upon it and re-radiates energy which is characteristic of this radiating system only, not dependent upon the type of radiation which is incident upon it.rom the assumption that the electromagnetic modes in a cavity were quantized in energy with the quantum energy equal to Planck's constant times the frequency, Planck derived a radiation formula.
