Question
This question is about red-shift.
The wavelengths of radio signals from galaxy A are found to be red-shifted from the wavelengths that would be observed from sources at rest relative to Earth.
The fractional change in wavelength of the radio signals from galaxy A is 9.4×10–3.
Calculate, in km s–1, the average velocity of galaxy A relative to Earth.
