Spectrophotometers employ various sources of light. Which of the following is NOT true for spectrophotometer light sources? O Dueterium arc lamps use controlled electric discharges to cause D; to dissociate and emit visible radiation. OA silicon carbide globar emits infrared radiation when heated to near 1500 K O Lasers emit radiation of a single wavelength. O Tungsten lamps emit radiation over the visible spectrum and parts of the ultraviolet and infrared spectrums. O Light emitting diodes emit narrow bands of visible and near-infrared radiation.
