Hey guys,

My physics assignment is about constructing a spectrometer and states: Make observations with your spectrometer of at least 4 different sources of light. At least one must be analysed quantitatively. For each spectrum, identify major features and explain their origin. A photograph of each spectrum must be included in your final report.

Could someone just clarify if 1) where it says "For each spectrum" it means like each different source of light (e.g. flashlight, laser etc) and also 2) where it says "explain their origin", what does this mean, does this mean what the light source is? 3) Also how do I set up the response to this question?

Thanks so much
