Answer the following question given this paragraph: 

Scientists studied the distinctive pink color of the gas discharge created by hydrogen gas. When a narrow beam of this light was viewed through a prism, the light was separated into four lines of very specific wavelengths (and frequencies since and are inversely related). An atomic emission spectrum is the pattern of lines formed when light passes through a prism to separate it into the different frequencies of light it contains. The Figure below shows the atomic emission spectrum of hydrogen.


Q: What do you call the pattern of lines formed when light passes through a prism to separate it into the different frequencies of light it contains?


A:
atomic emission spectrum
