Worksheet on Doppler shift analysis using star spectra.

A blurred image of a worksheet titled "SCI 4004 Mod. 3 Exercise" featuring a spectrum analysis task. The worksheet includes a lab spectrum and spectra of five stars (A-E), with instructions to rank the Doppler shift size from largest to smallest based on the position of spectral lines. The text explains that the left end of each spectrum corresponds to shorter wavelengths (blue light) and the right end to longer wavelengths (red light). A sample answer is provided, indicating the ranking order: C, B, A, D, E.

- Then, review the findings: After comparing all the stars, I can see that Star E's absorption lines are in the exact same positions as the "Lab Spectra". There is no shift to the left (blue) or right (red). This means Star E has no relative motion towards or away from the observer.
- Bring everything together: The star whose spectrum matches the lab spectrum, indicating no Doppler shift and therefore no relative motion, is Star E.
