A table of the visible light spectrum is shown below.

A 2 column table with 6 rows. The first column is labeled color with entries red, orange, yellow, green, blue, purple. The second column is labeled wavelength in nanometers with entries 700 to 635, 635 to 590, 590 to 560, 560 to 490, 490 to 450, 450 to 400.

Tyrone analyzes the emission spectrum of an unknown element. He observes two discrete lines at 600 nm and 650 nm, and he sees many lines corresponding to shorter wavelengths, with the strongest line being at 475 nm.

Which emission spectrum is Tyrone most likely analyzing?

Answer is C
