What are the characteristics of the radiation emitted by a blackbody - Please show me your calculations - Speech or Presentation Example Wien’s Law in particular, states that for blackbody 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 inversely proportional to absolute temperature (T). Mathematically, this law is stated as Peak Wavelength (ÃŽ ») = 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 amount of energy that is given off by the black body per second per unit area is always 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 Wien’s for mula, T = 0.29/ÃŽ ». Therefore, for the hottest where ÃŽ » = 200nm, the temperature = 0.29/200nm = 0.00145 and for the less hot object whose ÃŽ »= 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

But the echoes of the trial continue to linger through the corridors of time and that is a testimony good enough to understand the impact of the case on the British legal system as well as the attitudes of people and society towards crime and punishment. For instance, such terms as ‘crime passionnel (crime of passion)’ and ‘diminished responsibility’ that would otherwise have remained strictly confined to the arena of legal jargon are almost in the public domain today, and in this the contribution of Ruth’s trial cannot be understated. Whether or not Ruth deserved the penalty that she was given continues to be a matter of debate. But it is quite likely that those on either side of the debate confess that she stirred their conscience. In a country with a history of more than 90 per cent5 reprieve rate, it makes one wonder what made the British Home Office authorities of the time so stubborn in dealing with the pleas for a reprieve in Ruth’s case. If that was a move meant for strengthening the abolitionist cause, it did succeed eventually. Were this to be true, it might look unfai r that Ruth should have been victimized in the process, but it can be rationalized by calling a Ruth martyr rather than a victim irrespective of the truth. Most people would agree that, the law of the United Kingdom with regard to capital punishment, as it exists today, would not have taken that shape without Ruth’s execution. †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦ 5John Hostettler, A History of Criminal Justice in England and Wales (Hampshire: Waterside Press, 2009), 265. 6Nevertheless, it may be noted that even in 1965, when the UK Parliament resolved to end the death penalty, public opinion largely seemed to be in favour of keeping it probably because conventional th inking would lead us to believe that capital punishment could be a deterrent to murder. In spite of the infamous example of the Birmingham Six who had been doomed to spend seventeen long years in prison before their convictions were finally quashed by the Court of Appeal, the question of reintroducing the use of the gallows continued to be hotly discussed and in 1994, there was a even a legislative attempt to do so. It is a different thing that in the end, the motion was defeated by a large majority.7The implication is that there still seems to be in existence a significant
