3. The infrared camera image below shows a burning candle. The temperature scale at right is in C. What (spot) temperature do the crosshairs show the room to be at? Mark clearly on the image the hottest part of the flame. What is the temperature there? Spot 23.7 OC OFLIR 1500 23 2012-06-06 10:45 AM Use the Phet simulation at https://phet.colorado.edu/sims/html/blackbody- spectrum/latest/blackbody-spectrum_en.html to generate the blackbody spectrum corresponding to this temperature. Click on the magnifying glass above the y axis to make the spectral curve bigger. Carefully sketch the resulting graph on your answer sheet. Roughly how much of the radiation from this part of the flame is in the visible range? What spectral range is the rest of the radiation in? [Hint: Click on "Labels" in the simulation.] (10 pts)4. Color temperature. Given a choice of lightbulbs having color temperatures of 3000, 4000, 5000, and 6000 K, which one would you choose to provide illumination most like sunlight? Sketch the spectrum of light you would expect from such a bulb (remember to label the axes of your plot). (3 pts)
