What does hydrogens spectrum look like? How do the spectra of the elements compare with the spectrum of a light bulb and the spectrum of hydrogen?

The hydrogen spectrum is a "line" spectrum.  A light bulb produces a "continuous" spectrum like our sun, other stars and other objects that get so hot they produce visible light.  The continuous spectrum is more familiar to people with the colors blending one to the next.

When you look at a line spectrum it would be like someone painted black over a window when you were looking at a continuous spectrum and then cut small slits in the black paint a let only a small amount of light through where the slit was made.  The slits (lines) would be the right color for their location on the continuous spectrum but you would still be missing the rest of the colors covered by the paint.

Each gas has a unique set of lines for its spectrum, much like a finger print for the element.  Hydrogen's "finger print" has four lines that are in the visible part of the spectrum.  A red line along with a blue green and two in the viloet portion of the spectrum.  Since the red line is at one end of the visible spectrum, this line is far from the other three which are found at the other end of the visible spectrum.

Since the spectrum shows the colors separated what you would actually see is a bluish-purple light, a mixture of those four colors.
