- A pulsar is a rapidly spinning remnant of a supernova. It rotates on its axis, sweeping hydrogen along with it so that hydrogen on one side moves toward us as fast as 50.0 km/s, while that on the other side moves away as fast as 50.0 km/s. This means that the EM radiation we receive will be Dopplershifted over a range of ±50.0 km/s . What range of wavelengths will we observe for the 91.20-nm line in the Lyman series of hydrogen?

(b) Subtract the mass of the proton given from the mass of the hydrogen atom given . You will find the difference is equal to theelectron’s mass to three digits, implying the binding energy issmall in comparison.
