- The blackbody radiation emitted from a furnace peaks at a wavelength of 2.5 10-6 m (0.0000025 m). What is the temperature inside the furnace?A photon has a wavelength in a vacuum of 500nm, if its energy is doubled, what is the associated wavelength in a vacuum?A lightbulb manufacturer makes bulbs with different "color temperatures," meaning that the spectrum of light they emit is similar to a blackbody with that temperature. Assuming the emitting areas of the filaments in two bulbs with color temperatures of 2,000 K and 4,000 K are the same, which of the two is the brighter? About how much brighter is this bulb than its companion?
