Problem 20SEQ
Explain answer clearly, with complete sentences and proper essay structure if needed. An asterisk (*) designates a quantitative problem, for which you should show your work.
*Doppler Calculations. In hydrogen, the transition from level 2 to level 1 has a rest wavelength of 121.6 nm. Suppose you see this line at a wavelength of 120.5 nm in Star A and 121.2 nm in Star B. Calculate each star’s speed, and state whether it is moving toward or away from us.

ANSWER:
Step 1 of 3
To solve this equation, we shall have to apply the mathematical formula of Doppler shift, which is given as
…..(1)
Here,
radial velocity
shift wavelength
rest wavelength
speed of light
