Unformatted text preview: - Allow lamps to warm up before doing measurements. Task Notes:- Task 4: Find the Na-D doublet with a wide slit setting (~50 μ m), determine the calibration (and error) with and narrow slit setting (~10 μ m). - Task 6: The idea here is that the temperature of the tungsten filament is higher than the reading from the pyrometer due to the emissivity. Task 7: Measure the filament temperature, current, and voltage for 5-6 current settings of the bulb. Note that the current and voltage for the bulb are AC measurements. 1...
