- you are sitting at a desk in a completely dark room. the room is at normal indoor room temperature. there is an inanimate and un-powered object on your desk (e.g., a box, pencil case, notebook,...). what wavelength of blackbody radiation is emitted from that object with greatest intensity? (assume the object has the same temperature as the rest of the room.) express your answer in microns.arrow_forwardTo 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.
