Select all that apply. The spectrum of Star X is compared to a reference hydrogen spectrum. What can be concluded about Star X? https://clackamasweb.owschools.com/media/g_ipc_2014/11/doppler_shift_star_x.jpg Star X is showing radial motion. Star X is moving toward the Earth. Star X is moving away from the Earth. Star X may be moving, but its motion is not radial.

OpenStudy (unklerhaukus):

There is no shift right?

OpenStudy (unklerhaukus):

a shift in wavelength occurs: when there is a relative radial motion

OpenStudy (anonymous):

so it is the two last ones?

OpenStudy (unklerhaukus):

if it were moving away, (as in option c), there would be a red shift. but no shift is observed

OpenStudy (anonymous):

so just the last one?

OpenStudy (unklerhaukus):

\[\color{red}\checkmark\] If the star X is moving, it must be traverse motion (relative to the observer)
