The differences between the two observations is the sunlight spectrometer, light blends together and is hard to notice distinct changes where the light bulb shows clear lines and distinct changes through the spectrum.
It is this way due to elements from the sun have
much more where light bulbs are artificially made.
In the pictures below the left picture notes that is a picture of spectrometer at the light bulb, where the picture on the right is the sun.We can learn about the bulb or the sun is that
there are clear distinctions of measuring in nanometers through the
spectrometer.
