Problem 102

Quasars are among the most distant objects in theuniverse and are moving away from us at very highspeeds, as discussed in Chapter 16. Astrophysicists usethe redshift parameter z to determine the redshift ofsuch rapidly moving objects. The parameter z is determinedby observing a wavelength of a known spectralline of wavelength source on Earth; z /source ( source)/source. Find the speed of two quasarshaving z values of 1.9 and 4.9.
