# (a) Interpretation: The wavelength of maximum emission of a tungsten filament bulb at 2870 K and 3750 K needs to be calculated. Introduction: The Wein’s displacement Law states that the maximum wavelength in micrometers for the radiations of the blackbody is represented as follows: Λ m a x T = 2.90 × 10 3 Here, T is defined as the temperature in Kelvin as it is absolute temperature. Stefan’s law states that the total quantity of heat energy released per second per unit area by a perfect blackbody is directly proportional/related to the fourth power of the absolute temperature of its surface given by the equation: E t = aT 4 Where a has a value of 5.69 × 10 − 8 Wm -2 K -4
