WebIf they are false, correct them. (a) The total intensity of radiation emitted from a black body at absolute temperature T is directly proportional to the temperature. (b) As the temperature of a black body increases, the wavelength at which the maximum intensity is found decreases. (c) Photons of radio-frequency radiation are higher in energy ... WebThis radiation is emitted as electromagnetic radiation in the wavelength range of about 0.1–100 μm (1 μm = 10 −6 m = 1 micron). Some other areas of the electromagnetic spectrum are visible light (about 0.4–0.8 μm), X-rays (about 10 −11 m to 2 × 10 −8 m), microwaves (about 1 mm–10 m), and radio waves (about 10 m–30 km).
