Consider four identical stars moving with the following velocities relative to Earth:
Star A: 30,000 km/s toward Earth
Star B: 20,000 km/s away from Earth
Star C: 10,000 km/s toward Earth
Star D: 15,000 km/s away from Earth
Which of the following statements best describes the observed effect on the wavelength of light from each star due to their velocities?
A. The wavelengths of light from Star A and Star C will be blueshifted, while the wavelengths of light from Star B and Star D will be redshifted.
B. The wavelengths of light from Star A and Star B will be blueshifted, while the wavelengths of light from Star C and Star D will be redshifted.
C. The wavelengths of light from Star A and Star D will be redshifted, while the wavelengths of light from Star B and Star C will be blueshifted.
D. The wavelengths of light from all stars will be blueshifted.
