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 :

To determine which emission spectrum Tyrone is analyzing based on the observed wavelengths, we can use the provided table of the visible light spectrum and compare the wavelengths to the corresponding color ranges.

We have three observed wavelengths: 600 nm, 650 nm, and 475 nm. We need to find out which colors in the visible spectrum they correspond to.

1. 600 nm:
- We can compare this to the provided table.
- 600 nm falls between 590 nm and 635 nm.
- Referring to the table, wavelengths between 590 nm and 635 nm correspond to the color Orange.

2. 650 nm:
- We can compare this to the provided table.
- 650 nm falls between 635 nm and 700 nm.
- Referring to the table, wavelengths between 635 nm and 700 nm correspond to the color Red.

3. 475 nm:
- We can compare this to the provided table.
- 475 nm falls between 450 nm and 490 nm.
- Referring to the table, wavelengths between 450 nm and 490 nm correspond to the color Blue.

Based on these comparisons, the observed spectrum by Tyrone includes the colors Orange, Red, and Blue.
