Question

A star rotates about a vertical axis lying in the plane of the sky. Light of one spectral line is received from the top pole N , the bottom pole S , the left edge E (moving toward us) and the right edge W (moving away). Which statements are correct?

TestHub · Accepted Answer

Poles are on the axis, so there is no Doppler shift for either. The receding edge W is red shifted (longer wavelength) and the approaching edge E is blue shifted.
