What are the characteristics of the radiation emitted by a blackbody - Speech or Presentation

What are the attributes of the radiation emitted by a black body - Please show me your calculations - Speech or Presentation ExampleWiens Law in particular, states that for full radiator emissions, the higher its temperature, the higher either the frequency or the lower the wavelengths of the given predominant light emitted by the blackbody (Mahmoud 568). It can, as well be stated as the wavelength of maximum emitted radiation is often in return proportional to absolute temperature (T). Mathematically, this law is stated as Peak Wavelength () = 0.29/T, where T is in degrees Kelvin, and Peak Wavelength is I centimeters. In this respect, one characteristic of a blackbody radiation is its temperature. Stefan-Boltzmann Law, on the other hand states that the descend of energy that is given off by the black body per second per unit area is incessantly proportional to the forth power of the blackbody temperature. E = Sigma X Temperature to the fourth power (Mahmoud 568). From this law, the second characteristic of the back body radiation is the thermal energy possessed by the radiation. Basing on the Wiens formula, T = 0.29/. Therefore, for the hottest where = 200nm, the temperature = 0.29/200nm = 0.00145 and for the less hot object whose = 650nm, T = 0.29/650nm = 0.0004461539. from these results, it is clear that the hottest body is 0.00145/0.0004461539 = 3.25 times that other
