The melting point for tungsten, the element for the filament of an incandescent bulb, is about 3700 k, which examine figure 2.4 that gives temperature of 2000 k means that the filament probably does not get much hotter than about 3500 k expanded view of the blackbody curve for an object with a an blackbody curve for temperatures = 2000 k 14 12 10 0.8 0.6 0.4 0.2 2000 2500 3000 3500 1500 wavelength (nm) figure 2.4 9. (2 pts) assume that the temperature of the filament in the bulb at its dimmest 2000 k, so that its spectrum would look like the curve in figure 2.4. explain how we were still able to see some red in the spectrum of the incandescent bulb, even though the peak of the spectrum is well outside of the visible wavelength region. was around 10. (1 pt) if we could see at infrared wavelengths, would the bulb appear brighter dimmer? or 11. (2 pts) there would they appear bright are many stars that have surface temperatures in the 3500-2000 k range or dim to us? explain. 000k paueju 00s 00e. 0aen kusuaju ou jo aunseou y
