← ScienceWhich outcome follows within a spacecraft experiencing constant acceleration?
A)Artificial gravity matches Earth's
B)Internal temperature consistently decreases
C)Electromagnetic radiation red shifts✓
D)Cosmic ray arrival rate declines
💡 Explanation
The equivalence principle dictates effects of acceleration mimic gravity; causing photons to lose energy through gravitational redshift during their trajectory, because of the potential difference, resulting in longer observed wavelengths, therefore C rather than temperature changes.
