Experiment #5: Spectroscopy Flashcards
Calibration
Observe Hg discharge tube, record colour and scale
Hydrogen discharge tube
Observe and record
Emission Spectra of unknown sample
Observe and identify
Emission Spectra of Metal Chloride salts
Curl metal wire, fill beaker with DI and dip wire in, hold over flame x3
Dip in salt, hold over flame, observe
What was different about fluorescent lights and incandescent lights?
Fluorescent had prominent lines in a continuous spectrum, incandescent lights are a continuous spectrum
Why was there prominent lines in the flurorescent lamp?
Fluorescent lights have mercury vapour in them, resulting in the most prominent lines matching with mercury’s emission spectrum
