2. In one experiment, the spectra of an incandescent lamp behaving as a black body were measured with a temperature T, an emitting wavelength of peak intensity A, and an electric current I, if the potential difference was increased. The drop across the filament is 8 times and the current through it is doubled. What is the wavelength emitted at the maximum intensity? Given that the electrical energy can be converted to heat energy without loss. waste of energy
