Given what we know, we can confirm that when a noble gas is heated and the emitted light is shone through a prism, we can observe the emission spectrum.
These can be described as lines of different colored lights. These lines will be the observed results after heating the gas and shining its light through a prism. This emission spectrum can provide important information regarding the chemical composition of its source.
Therefore, we can confirm that the emission spectrum, described as lines of varying colors, is what we observe when a noble gas is heated and the emitted light is shone through a prism.
