Tyrone analyzes the emission spectrum of an unknown element. He observes two discrete lines at [tex]$600 \, \text{nm}$[/tex] and [tex]$650 \, \text{nm}$[/tex], and he sees many lines corresponding to shorter wavelengths, with the strongest line being at [tex]$475 \, \text{nm}$[/tex].

Which emission spectrum is Tyrone most likely analyzing?

To determine which colors in the visible light spectrum correspond to the observed wavelengths 600 nm, 650 nm, and 475 nm, let's examine the ranges provided in the table and match them to the observed wavelengths one by one.

1. For the wavelength 650 nm:
- According to the table, the range for Red is 700 nm to 635 nm.
- Since 650 nm falls within this range (i.e., [tex]\( 635 \leq 650 \leq 700 \)[/tex]), 650 nm corresponds to the color Red.

2. For the wavelength 600 nm:
- According to the table, the range for Orange is 635 nm to 590 nm.
- Since 600 nm falls within this range (i.e., [tex]\( 590 \leq 600 \leq 635 \)[/tex]), 600 nm corresponds to the color Orange.

3. For the wavelength 475 nm:
- According to the table, the range for Blue is 490 nm to 450 nm.
- Since 475 nm falls within this range (i.e., [tex]\( 450 \leq 475 \leq 490 \)[/tex]), 475 nm corresponds to the color Blue.

Summarizing these findings:
- The wavelength 650 nm is Red.
- The wavelength 600 nm is Orange.
- The wavelength 475 nm is Blue.

Therefore, Tyrone is observing the emission spectrum with distinct lines at:
- Red (650 nm)
- Orange (600 nm)
- Blue (475 nm)

These observations indicate that the element he is analyzing emits light corresponding to these colors in the visible spectrum.
