- To measure temperatures, physicists often use the variation of intensity of EM radiation emitted by an object. The wavelength at which the intensity is greatest is given by the equation: λmaxT = 0.2898 cm.K where λmax is the wavelength of greatest intensity and T is the temperature of the object in kelvins. In 1965, microwave radiation peaking at λmax = 0.107 cm was discovered coming in all directions from space. To what temperature, in a) K b) °C c) °F, does this wavelength correspond?arrow_forwardA blackbody is a substance that absorbs radiation of all wavelengths and radiates in a continuous spectrum at all wavelengths. It is given the name blackbody because an object that absorbs light at all wavelengths appears black to the human eye. By the end of the 19th century, several properties of blackbody radiation had been established. First, the total intensity I (the average rate of radiation of energy per unit surface area) emitted from a blackbody was shown to be proportional to the fourth power of its temperature: I=oT¹ This is called the Stefan-Boltzmann law for a blackbody. The constant of proportionality o is known as the Stefan-Boltzmann constant and was determined to be o = 5.67 x 10-8 W/(m². K¹). It had also been discovered that the wavelength at which the radiation intensity was maximum varied inversely with temperature. This result, known as the Wien displacement law, is written AmT = 2.90 x 10-³ m. K. where Am is the wavelength with the greatest radiated intensity. ✓…arrow_forwardYou are using a radiometer to observe the thermal radi- ation from an object that is heated to maintain its tem- perature at 1278 K. The radiometer records radiation in a wavelength interval of 12.6 nm.
