WebElectromagnetic Radiation is basically light, which is present in a rainbow or a double rainbow. It also is a spectrum consisting of radio waves, microwaves, infrared waves, visible light, ultraviolet radiation, X-rays, and gamma rays. There are only two ways to transfer energy from one place to another place. Through a particle. Through a wave.

WebA body for which a(λ) = 1 for all wavelengths is a black body. A body for which a has the same value for all wavelengths, but less than unity, is a grey body.
